Volcano Map
This visualization displays the global distribution of historically significant individuals from the Pantheon dataset, where each circle represents a person positioned by birth location. The map uses equal-area natural Earth projection with graticule lines, and circle size encodes the Historical Popularity Index (HPI) using a square-root scale. The accompanying date histogram enables time-brushing to filter the map through linked selection. Built with React, the implementation leverages D3 modules including `geoNaturalEarth1`, `geoPath`, `scaleSqrt`, and `scaleTime`, while tooltips employ the Tippy library.
AI-generated descriptionI plugged the Pantheon dataset into this dataviz template provided by Curran Kelleher.
Each dot in this map is a person with a Wikipedia bio in 15+ languages.
This is a work in progress! Apologies if it kills your browser.
Update: I've filtered the dataset by gender (Women only) to reduce load while I get it working.
Todo:
- Add a drop-down/interactive legend to be able to filter dataset by occupation.
- Add Zoom.
- Solve circle overlapping problem by implementing Voronoi tooltips.
