ebola cases
This interactive map plots Ebola cases as cyan dots over satellite imagery, with each dot representing a reported location across multiple countries, including Guinea, the Democratic Republic of the Congo, Spain, and the United States. The visualization combines D3.js with Mapbox’s Leaflet library, using a custom SVG overlay that projects geographic coordinates into pixel positions via `map.latLngToLayerPoint`. Dots animate from a small radius to a larger size, and the map re-renders positions on zoom or pan events. The data comes from a GeoJSON FeatureCollection containing point geometries with country and address attributes.
AI-generated descriptionThis is a simple setup of Leaflet (via Mapbox) with d3 to show dots on a map. This can serve as a base for many interesting geographically based visualizations
Nice overview of using d3 + Leaflet. I found this slightly simpler to use than Mike's classic post.
