The visualization presents crime data across San Francisco neighborhoods for a selected year, combining donut charts for offense type distribution and bar charts for hourly incident patterns. Each donut chart displays the share of crimes by neighborhood, with the total count centered and interactive hover labels revealing specific neighborhood names and values. The bar charts beneath show the frequency of incidents across 24 hours per offense type. Built with CoffeeScript, it uses D3.js primitives including `d3.svg.arc`, `d3.layout.pie`, and `d3.scale.ordinal` for coloring, while the JSON data source is loaded via `d3.json` from the `top-neighborhoods-{year}.json` endpoint.

Fork of D3: NYC Crime Visualization

This interactive visualization explores NYC crime data through a coordinated multi-view dashboard. It combines a geographic heatmap using `d3.geoMercator` and `d3.geoPath` to display precinct-level crime intensity, with a donut chart (via `d3.arc`) breaking down crime types by color. Three bar charts for age, race, and additional demographics update alongside. The SVG-based scene includes a legend, tooltip, and reset button, with all sub-graphs animated over a 24-millisecond duration. The interface supports dynamic filtering by precinct and crime type, using `d3.scaleOrdinal` and linear/band scales for color and axes.

modified for voronoi

This example visualizes SFPD incidents by neighborhood in 2016, combining both a bar chart of average incidents and a line chart showing incident trends over time. Each neighborhood’s bar and corresponding line are linked, with mouseover highlighting the active district and click filtering to show only that district’s line. The code uses d3.nest() to aggregate data by district, d3.scaleBand for the bars, d3.scaleTime for the date axis, and d3 transitions for interactive animations. The data is loaded from the SF Open Data JSON API, and the visualization renders with SVG.

Fork of NYC Crime

This visualization of NYC crime data combines a choropleth map, a donut chart, and bar charts in a single SVG canvas. The map uses D3’s `geoMercator` projection to display precincts, while the pie chart and bar plots show crime type, age, and race distributions. Interactive filters let users select a precinct or crime type, updating all views. Built with D3 v6 and React, it uses SVG for rendering and features a reset button for clearing selections.

Fork of Fork of D3: NYC Crime Visualization

This interactive dashboard presents NYC crime data across multiple coordinated views: a geographic map with a heatmap overlay, a pie chart, and two bar charts for age and race breakdowns. Users can filter by precinct and crime type, with all charts updating in response. The visualization uses D3 v6 with a Mercator projection via `d3.geoMercator()` and `d3.geoPath()` for the map, alongside SVG-based pie and bar charts. Crime color mapping and tooltips provide additional detail.

Fork of D3: NYC Crime Visualization

This dashboard visualizes NYC crime statistics across multiple coordinated views: a geographic map shading precincts by crime volume, a pie chart of crime type proportions, and bar charts breaking down arrests by age and race. Users can filter the entire interface by clicking map regions or crime categories in the pie. Built with React and D3 v6, it uses `d3.geoMercator` and `d3.geoPath` to project the map, `d3.arc` for donut slices, and `d3.scaleBand`/`d3.scaleLinear` for the bars. A color legend uses CSS linear gradients, and an SVG animation resets the view when the button is clicked.

D3: NYC Crime Visualization

This interactive NYC crime visualization presents multiple coordinated views: a choropleth map of precincts, a pie chart of crime types, and bar charts showing age and race distributions. Users can click precincts or crime categories to filter across all views, with a reset button to restore the full dataset. The visualization uses D3 v6 with d3.geoMercator and d3.geoPath for the map projection, d3.arc for the pie chart, and d3.scaleBand for bar charts. Crime data is color-coded via a linear gradient legend and tooltip interactions.

Fork of NYC Crime

This interactive dashboard presents New York City crime data through a synchronized map, pie chart, and bar plots. A choropleth map visualizes precinct-level data, while a donut chart breaks down crime types and bar charts show age and race demographics. Users can filter the visualization by clicking on map precincts or the reset button. The code uses D3.js v6 with `d3.geoMercator` projection, `d3.geoPath` for map rendering, and SVG for all graphics.

exploration&Visu

This visualization uses D3 v4’s `d3.histogram` and `d3.scaleBand` to display crime counts as bar charts, with hardcoded arrays for daily and monthly totals. The SVG chart is generated via a reusable `chart` function, which sets up linear scales and an axis, then binds data to rectangle elements for bars. The code includes category labels for crime types and weekdays, but no external data file. Rendering is purely SVG with styled bars and axes.
