Fork of Coronavirus Deaths Over Time by Country With Voronoi Overlay

This visualization displays the cumulative number of COVID-19 deaths over time for each country, with a Voronoi overlay enabling interactive highlighting. A log-scaled y-axis and time-scaled x-axis render the line chart, while the D3 Delaunay triangulation (`d3.Delaunay`) and Voronoi diagram compute proximity regions for each data point. Hovering a cell triggers a React state update, redrawing a country's line in bold black. Data is sourced from the Johns Hopkins CSSE COVID-19 dataset, rendered as SVG.

Fork of Migrant Deaths Linked Views with Fast Brushing

This interactive visualization links a world map with a time-series histogram to explore migrant deaths. The map displays circles scaled by the total number of dead and missing migrants, while the histogram shows the same data aggregated by month. Users can brush over the histogram to filter the map dynamically. Built with React and D3 v5, it uses `geoNaturalEarth1` projection and `brushX` for interaction. Data comes from the Missing Migrants Project, with country boundaries from the World Atlas TopoJSON.

Fork of Multiple Views Cleanup

This visualization combines a bubble map and a histogram to explore global migrant deaths. The map projects city coordinates using `d3.geoNaturalEarth1` and `d3.geoPath`, with bubble sizes scaled by the square root of the "Total Dead and Missing" value. Beneath it, a time histogram bins events by month using `d3.bin` and `d3.timeMonths`. Data comes from the Missing Migrants Project CSV, while country boundaries use the World Atlas TopoJSON. The React-based SVG rendering separates concerns into modular components for marks and axes.
