Fork of Multiple Views with Brushing
A world map of coffee bean exports uses a linked DateHistogram to filter cities by year through brush-driven interaction. The BubbleMap renders d3.geoNaturalEarth1 projections with d3.geoPath for country boundaries and graticules, while circles scale by export value. The DateHistogram bins data by month using d3.bin and d3.timeMonths, with d3.brushX enabling temporal selection that filters the map in real time. Data comes from a CSV via d3.csv, with world atlas geometries from topojson.
