Fork of Fork of 112 Multiple Views
This example presents a synchronized multiple-view visualization of 112 emergency call data across the Netherlands. A bubble map displays the geographic distribution of incidents, with a brushable time-series histogram below it that filters the map to show only incidents within a selected date range. The map uses a D3 geoMercator projection with d3.geoPath to render municipality boundaries from TopoJSON, while circles mark individual incident locations from CSV data. The histogram relies on d3.bin and d3.brushX for interactive temporal filtering. React manages the component state and rendering, with SVG used for all visualization elements.
