Homework 10 - Annotated map
Overview: In this assignment we’ll work on one of the most common and interesting types of visualiztions: Geo-spatial visualizations. In other words, maps! These types of visualizations can be a little more work to put to gether than what we’ve seen previously, so we’ll only focus on creating a single visualization, but we’ll try to make it as informative as possible. Specifically, we’ll explore using annotations to point our readers towards particular points of interest in our visualization.
Requirements:
Choose a public dataset that includes lattitude and longitude variables, along with at least one other variable.
There are no strict restrictions on what dataset you choose, but you should aim to choose a dataset that is unique and insightful.
You will likely also want to choose a dataset that requires little preprocessing if possible.
Take a look at the data resources page for inspiration.
Visualize this data as a map, encoding longitude to the x-axis and lattitude to the y-axis. Other encodings are up to you.
Your visualization could be any type of geo-spatial visualization, depending on what is most appropriate for your data (e.g. a geo-scatter plot, heatmap or choropleth).
If geographic and/or political boundaries are not a part of the base visualization (e.g. in a choropleth), make sure to include them for context. A reader should be able to quickly and intuitively understand where in the world each observation is located.
Add at least 2 annotations to your visualization that point out specific locations/observations and highlight why they may be relevant and important to the reader.
- For example, John Snow’s cholera visualization pointed out the location of the Broad street pump. A visualization of wildfire risk might point to specific cities that are large and at high risk.
Make sure to include clear explanatory captions for each visualzation. In this case, each caption should highlight what a reader could take away from it.
Cite and provide a link to the source of the dataset used.
