For this assignment, you will visualize geospatial data using d3.
Here are the specifications for this assignment.
To get a C (75) do the following:
- Download a spreadsheet from https://www.ers.usda.gov/data-products/county-level-data-sets/download-data/.
- Modify the spreadsheet to generate a CSV file
- Create a Choropleth map for the data.
To get a B (85):
- Download the expensive states CSV
- Combine this data with the latitude and longitude of the centroid of each state. This information can be found at online.
- Modify the expensive states file with the latlon information.
- Create a proportional symbols map for any variable in the data.
To get an A (95):
- Implement interaction (tooltips) for both your examples - the Choropleth map and the proportional symbols map
- Highlight the top 10 most expensive states in the proportional symbols map using a different color
- Create a choropleth map for the world for a dataset of your choice that includes tooltips.
To get an A+ (100):
- Generate a geovisualization of data for any other country at a level lower than the states/provinces level
Submitting the assignment
- For every visualization, post a link to your Vizhub sketch (mark it private, invite the TA and me as collaborators) and test it out before posting a link to it on your own website.
- Submit a link to your website on Canvas.
