Choose: An example of how you made a choice related to visualization type

For my Pittsburgh dataset project I compared the number of trees in different Pittsburgh neighborhoods using a bar graph.

Reflection: If you could convert this visualization to something else (bar graph vs. scatter plot, etc.), what would you choose? How would might user experience change if you made this change?

If I were to redo this visualization it might be better as a bubble chart. After making some bubble charts for out group project, I think it would be interesting to see how that would represent the data.

Choose: An example of how you made a choice related to color, fonts, captions, scale, or other design elements

For the Pittsburgh dataset project I had to pick the design of the map that I wanted to use for my heat map. I picked a pretty basic theme so that it didn't distract from the data.

Reflection: Discuss how you would change these design elements under different circumstances, especially in terms of your imagined audience. How would you revise for an expert on your topic, or for someone who knew nothing about your topic?

If I were going to change the theme to appeal to someone who knew nothing about my topic I might have picked something a bit more interesting and colorful so that the map and page aren't so plain and white. There were some maps with parks, water, and other features color coded which would make it easier for someone not familiar with Pittsburgh to better understand the data. Someone more familiar with the data might be more interested in the specific neighborhoods and types of trees so a plain theme with labels would work better.

Choose: An example of how you made a choice related to comparing on thing to another

The bar graph from my Pittsburgh dataset project comparing the number of trees in each neighborhood.

Reflection: Why did you choose this particular comparison? Would the comparison be more effective with additional revisions? If so, what revisions?

This comparison was interesting to me because it shows how trees are distributed throughout Pittsburgh. This comparison would probably be more effective if it included more information about the different neighborhoods like the average income of residents or population to see if there are any correlations.

Choose: An example of something that frustrated you or took a larger amount of time than you would have liked

When working on the skills assignment where I was learning how to use Mapbox it took a really long time to figure out how to get the popups to work. I spent a lot of time trying to figure out how to get it to work and looking at tutorials and documentation but I couldn't figure out why it wouldn't work. Even after using the code from the tutorials which should have made sure that it worked but it still wouldn't.

Reflection: How did you finally overcome this obstacle, or when did you know it was time to move on? What did you learn, procedurally, from this obstacle?

I finally found out that popups aren't supported when clicking on a heat map. To get it working I needed to create a duplicate layer on the map and add the popups to that layer instead of the heat map. I then made this layer transparent so it didn't get in the way of the heat map, but still get you see the popups.

Choose: An example of something you are particularly proud of

I'm most proud of the maps I made for my skills project, specifically a map you can add custom points to and adding filtering to my tree heat map.

Reflection: Why does this example stick out in your mind? How might you adapt what you like about it for future work?

I'm proud of these maps because I basically figured out how to make them on my own and I think they are useful features. This is pretty similar to my normal process because I often find things I want to make and figure out how to make it work.
