This interactive map of New York City’s five boroughs visualizes traffic crash statistics, distinguishing injury and fatality counts for cyclists, pedestrians, and motorists. A legend allows users to toggle six incident categories on and off, revealing colored point markers for each crash location. The map renders boroughs as colored SVG paths using `d3.geoMercator` and `d3.geoPath`, with data loaded from CSV files via `fetch`. Hovering over a borough displays aggregated crash counts from `CrashByBorough.csv` in a tooltip.

Interactive NYC Borough map

An interactive map of New York City's five boroughs, colored distinctly, serves as a base for exploring traffic crash data. Users toggle checkboxes in a legend to display layers of colored points representing injured or killed cyclists, pedestrians, and motorists. The map shows these incident locations as colored circles at varying opacities. Hovering over a borough reveals a tooltip with summary crash statistics. Built with React, it uses D3's `geoMercator` for projection, `geoPath` for drawing, and `topojson-client` for handling geographic data, visualizing point data loaded from CSV files.

Interactive NYC Borough map with scroll and zoom

An interactive map of New York City boroughs visualizes traffic crash data, representing the locations of injured and killed cyclists, pedestrians, and motorists as colored points. Users can zoom towards the cursor with the mouse wheel and pan by dragging, while toggling the visibility of six incident categories via a legend. Built with React, the map is rendered as SVG using D3’s `geoMercator` and `geoPath` for the geographical projections. Crash statistics are loaded from a CSV file, and the incident coordinates are read from separate CSV files per borough.

Interactive NYC Borough map with scroll and zoom

An interactive map of New York City's five boroughs colored by name, with an optional overlay of incident points. Across each borough, users can toggle visibility for six crash-related categories—cyclists, pedestrians, or motorists, each further split into injured or killed—using checkboxes or clicks in the legend. The React app loads data from CSV files for incident locations and a TopoJSON file for borough boundaries, rendering with D3's Mercator projection and `geoPath`. Hovering over a borough displays a tooltip with aggregate crash statistics from a separate CSV.

More Optimized Interactive NYC Borough map with scroll and zoom

This interactive NYC borough map visualizes traffic crash data, showing both aggregate borough statistics and individual incident points for cyclist, pedestrian, and motorist injuries and fatalities. Users can pan and zoom with mouse wheel and drag gestures via a debounced render pipeline. The visualization combines an SVG layer for borough outlines rendered with `d3.geoPath` and `geoMercator`, alongside a Canvas layer for efficient point rendering. Incident data is loaded from per-category CSV files, while a legend toggles visibility for six incident categories using React state.

NYC borough map with interactive legend

An interactive map of New York City's five boroughs displays traffic crash counts from a CSV dataset as circular markers with numeric labels, overlaid on a TopoJSON-derived GeoJSON map. Users hover over legend items or borough polygons to highlight matching regions while dimming others. The visualization uses React for component state and layout, D3 v7's `geoMercator` and `geoPath` for the map projection, and `select` for SVG updates. A semi-transparent legend communicates the fixed borough color scheme.

NYC Crash Point Map with interactive legend

This interactive map displays motor vehicle crash locations across New York City's five boroughs, with each borough filled with a distinct color. A legend allows users to hover over borough names, fading non-selected areas to highlight crash density in a specific region. The visualization uses React with d3.geoMercator and d3.geoPath to project TopoJSON boundary data from `nyc_boroughs.topo.json` into SVG paths. Crash points from a CSV file are rendered as small black circles, with positions calculated via the projection function.
