I'm really impressed with how passionately you talk about your class and your work, and I think your project to share your classes story captures that enthusiasm well. I really enjoyed your explanation of your data visualization, and I thought the colors were quite pretty. Since you said that the colors were only there because it was a static image, and it would help show which heart rates were faster and slower, I wondered what colors you would intend to use in the actual representation. Would each person have their own designated color, so you could follow one particular story line? Or would it be more uniform to better show the story of the entire class? Overall, I find it to be a great idea to artistically shows the intrinsic data behind a interesting creative process.
This has the potential of creating a very beautiful piece. It would be awesome to have it be an interactive map where each student could see which dot on the piece was theirs. That way, just like the heart-beat light bulbs in the examples, each user could connect more intimately with the piece, given that they can see their contribution to its creation. Additionally, it might be of value to somehow mark the transition from one dot to another (for the same person) through some sort of flow-y graphic. (to make it easier for people to follow their own dot transitions over the entire piece)
Overall, this was excellent!
I really like the design of your graph. It is very pretty and agreeable. But I am not sure how you are going to capture the heart beat data, seems like you are using a dynamic way to represent them. One suggestion I have is that why not make the y-axis as heart beat rate, then the beautiful skin temperature graph can be a bell-shaped one(since in the middle of the class, the heartbeat rises). Then you can include both heart beat and temperature in the same static graph.
I think this data visualization is beautiful, and truly does tell a story. I used to take dance classes, so I understand how much energy can change throughout the course of the class, and I think that recording heart rate and skin temperature data does a great job of capturing that. I also think it would great if a dance instructor could see this visualization to get an idea of how those in the class are feeling. Just from a quick glance, an instructor could see that maybe the students have been working very hard and are ready for a cool down, or perhaps the opposite. I am curious, though, if the y-axis represents any sort of data as your data visualization is designed currently? In your example image, the dots seem to move down a little in the middle, and I wonder if there is an explanation behind that. All in all, I think this is a great data visualization; it is beautiful, useful, and makes it easy to understand the data!
To clarify for everyone, the y axis is currently nothing other than an artistic choice. The heartbeat isn't shown here, since it would be represented by the pulsing of the dots if this were a real version. Sorry that wasn't clear! I'll have to think more about the idea of being able to trace individuals. I didn't think about it originally because I was more focused on the group as a whole, but maybe there is a way to incorporate that. Thanks everyone!
I think with the variables you picked, you can definitely create an amazing visualization from it. Using different colors/shapes to represent each creates large potential for an interesting piece. The data you picked is practical to accumulate too. Though I question skin temperature as I think there could be too many alternate factors influencing it. But who knows, that much just make it more interesting.
