1116 Taiwan Earthquake
This visualization explores Taiwan’s earthquake patterns from 1973 to 2024 using a d3-geoMercator map and an interactive scatterplot. Users can filter by year and select attributes for the x-axis, y-axis, and color encoding, while hovering reveals tooltips. The code uses d3.json and d3.csv to load TopoJSON county boundaries and earthquake records, with d3.geoPath rendering the map. A heatmap additionally shows earthquake frequency across magnitude ranges over time, built with d3.scaleOrdinal.
