Number of Galls on Main and Lateral Stolons

By Linda Shi

This model represents data collected by counting the number of galls found on main and lateral stolons of Whiplash. The four sizes of rings represent four stages of stolon growth from largest to smallest; we see the stolons in their old to super young stages. I have also chosen green zip ties to be the colour for main stolons whereas black ones represent lateral stolons. 
By building this physical model, I’m able to see, group by group, on what type of stolon or which stage of stolon growth is the wasp more prone to lay their eggs. I’ve noticed that on the main stolon, wasps are more attracted to the young and super young stages of the stems, whereas on the lateral ones, more galls are found in the oldest stage of growth. One thing to keep in mind is that the lateral stolons sprout later than the main stolons. This difference in time could potentially result in the differences we see between galled stolons. I’m interested in the potential architectural installation of this model. In a built project, I want to see people become part of the data and have a 1:1 scale interaction with it.

Cloud of Rings

By Linda Shi

In my final project, I’m taking the data I learned from Project one and the skills I’ve accumulated from Project two, to put together a larger skill installation in the presentation space. 
My Cloud of Rings, instead of using the different sizes of rings to represent different stages of plant growth, I’m using the thickness of the rings to do so. By reversing the dark and light colors of the stolons, this color representation of the main and lateral stolons are more accurately displayed. Since the main stolons have grown for longer periods of time, they are thus represented by the darker colors. 
Having the Cloud hang right above the hallway, I invite visitors to walk under the installation. The six strings hanging the are proportional to the number of total galls collected from each study. 
The rings above overlap each other, creating various densities in the surface mesh. I hope this creates an interesting experience for those who walk below it. I hope to bring this project further by becoming more proficient at Rhino and Grasshopper. I would also like to use the 3D printer to construct smaller mock-up models of future interactions.

Galls on Main and Lateral Stolons Voronoi Map

By Linda Shi

Taking the physical mock-up model one step further, my second project renders a pattern that evokes the same set of data from my first project.

Using 3D modelling software, Rhinoceros, and its plug-in parameter modifier, I was able to manipulate geometries on the plane. Using the parameter Voronoi, the maximum area is drawn around each point defined on the plane. I’m drawn to the mathematical and structural properties of the pattern, creating interesting dynamics between each of the defined points:

I want to use this pattern to represent the data collected. This pattern can easily be translated into a surface or screen that defines a specific architectural space. This will allow people to interact with data while navigating around the architectural installation.

This sketch represents the average number of galls in each of the six greenhouses that the bio-control experiments were carried out in. Each square represents one of the greenhouses, and the saturation of the colour is indicative of the average number of galls that had been created by the gall wasps at the end of the experiment. The idea here was to take the data back into the environment from which it came, and possible reveal new information about the space itself, and how that could have contributed to the production of galls or “fertility” of a particular greenhouse.

I was later made aware that some of the experiments were started later than others, which contributed to the low fertility rate in the top-leftmost greenhouse square. However, this data visualization led me to ask the questions necessary to learn more about the experiment than I had expected.

Galled vs. Ungalled Portions of Hawkweeds

By Morgan Bath

All of the projects that I created this semester dealt with only the galled vs ungalled and did not focus on the lateral and the stolen figures. The works on paper are drawings of hawkweed seeds which were then manipulated to represent the ungalled portions of the plant that still have the ability to grow and the holes represent the lack of growth that the gulls created. The colours of the papers represent different plant growth stages as well as in the colour of the warp strings on the weavings I started.

The sounds piece that accompanies the works on paper is a creation from using the data provided for each plant stage and using the frequency of each number to create ten-second interval sounds of each plant stage and type. This piece I think was very successful, it is straight forward but I don’t think it is too literal, like the other pieces, right up front. I used two types of sounds wave one to represent galled and one ungalled and then just inserted the data set into the program to generate the sound clips.

Re-Assessing Stolon Growth with Attention to Galling in Hawkweeds

By Keith Morgan

My previous visualizations had given me a few assumptions about the trial that seemed to go against some of the hypotheses of the researchers. I had come across a trend that seemed to show that when introduced to the biocontrols at certain ages, the hawkweeds tended to grow more stolons rather than fewer. What I had not taken into account when exploring this was what the galls themselves were doing: how were the galls dispersed on the plants, and did this have an effect? Again, I severely averaged out the data, this time combining all of the trials and all of the ages for the test group as one entity, and the control group as another. The key metrics for this visualization were the total average number of main and lateral stolons that grew on one plant, the average number of main and lateral stolons that had galls, and finally the average total number of galls per plant. Assuming that a galled stolon is considered ‘dysfunctional’, these new numbers actually reversed my original assumption that while galled plants tended to have more stolons on average, they actually had fewer ‘functional’ stolons. In my visualization, only these functional stolons grow to full length.

Comparing Gall Formation on Main and Lateral Stolons in Whiplash and Mouse Ear Hawkweeds

By Keith Morgan

This was my first encounter with the data set, so in order to get familiar with the metrics and patterns in the data, I chose a straightforward representation to keep myself grounded. I attempted to show the number of main and lateral stolons that had been galled, in addition to the total number of galls that had formed on each species. These sets were expressed as the height of each collection of blocks in relation to the top of the clear walls on the sculpture. 
My process involved combining the data from all of the ages of the plants in each trial so that the comparison was left to differences between species instead of age. What this allowed me to do was show that proportionally speaking, the Whiplash species had more main stolons galled, while Mouse Ear had more lateral stolons galled. Still, when we look at the total number of galls that grew, it became apparent that both species grew an almost identical number of galls.

Crocheting the Relationships Between Galled and Ungalled Stolons

By Taelynn Graham

This visualization uses the exact same data as my interactive digital visualization. I decided to represent the length of each section with crochet stitches, and they became quite lengthy, which shows how much spreading the Hawkweed plants actually do. I want people to be able to really understand the proportion of stolons being galled, and having a tangible object that you can hold and stretch out really shows this in a way that isn’t quite as easily understood by looking at a digital shape. 
My intent was to keep the colours the same for both visualizations, so that viewers an easily move from one visualization to the other and be able to recognize that these are in fact the same pieces of data. The mounted crochet strips with a single strand down them represent the stolons galled and the average number of galls on these stolons. This is an added piece of data included to show how many galls exist in each section, and what it means in comparison to the proportions of galled stolons. Just because there are a lot of galls does not mean that the proportion is substantial.

Galled vs. Ungalled 3D Bar Graphs

By Corwin Smith

For this representation I wanted to show a comparison between galled and ungalled stolons in Whiplash. The green graphs represent the main stolons of Whiplash, and the yellow represent the lateral stolons of Whiplash. The graphs are separated into rooms, and then ages of the plants within the room. I always find 3D graphs on the computer to be very bad because of perspective, so I wanted to see if that same problem comes through when 3D printing the graphs of data. They were luckily much more effective as an actual 3D object than on the computer, and really allowed an interesting interaction from the viewer as they held it and were able to touch and look at it from all different angles.

Stolon and Gall 3D Print

By Corwin Smith

This stolon and gall 3D print was made to show a larger scale representation of what the data was being collected from. Cylinders that fill the galls on the inside of the stolons give information about galled versus ungalled stolons relating to the age of the plant. This stolon shows the data collected from the main stolons of Mouse Ear. I was hoping to show what the stolon looked like with the galls to add to the understanding of what is being represented by this data. The cylinders used to represent area inside a gall were used to show the ratio between galled and ungalled in the different ages.

Total Gall Count in the Main and Lateral Stolons for Mouse Ear Hawkweed

By Corwin Smith

The graphs represent the total gall count in the main and lateral stolons for Mouse Ear. The red represent lateral, yellow represents main, and green represents the total of both main and lateral. I was hoping to create these graphs to give an interactive aspect to them, where the user may swap them out and compare the different aspects of the data very easily.

Since it is a 3D object and can be moved around and interacted with, it brought a very unique feeling to the data when viewed the first time. It allowed myself to display a lot of data points efficiently and without the clutter that would happen with a similar 2d representation. This would allow them to compare parts of the data they need to.
