In this hands-on talk we visualize a publicly available, spatial dataset using Altair. Starting gradually from an example to see the declarative pattern in action to a geospatial chloropleth map to a layered chart with circle markers and finally to showing spikes that impart it a 3D touch. However, getting custom shapes to show on charts is not well documented. Moreover, by default the markers increase in area (based on the quantity of data it represents) which is not what we want. So by using techniques that are not well documented the audience will learn how to make an interactive geospatial graph which is also being actively used by The New York Times and The Economist’s graphics teams for their covid visualizations and which has been received very well by the data visualization community.
