A choropleth map displays U.S. county unemployment rates for August 2016, colored with a quantile scale and the d3.interpolateInferno palette. A brushable histogram below the map visualizes the rate distribution; brushing it highlights matching counties on the map with d3.brushX. Pan and zoom interactions rely on d3.zoom and d3.geoPath with a geoAlbersUsaTerritories projection. The map renders via SVG using TopoJSON county boundaries from the us-atlas dataset.

AI-generated description

An adaptation of the D3 Choropleth Example that uses vanilla JavaScript and adds a brushable histogram. Shows Unemployment rate by U.S. county, August 2016. Modified to add zooming, leveraging utilities from d3-rosetta.

Map

This visualization presents a choropleth map of U.S. county-level unemployment rates, where each county is colored according to its rate using a quantile color scale from the Inferno palette. The map uses D3's `geoPath` and `geoAlbersUsaTerritories` projection to render county and state boundaries from TopoJSON data. A linked histogram at the bottom allows for interactive brushing to highlight counties within a selected unemployment rate interval. The example demonstrates the D3 General Update Pattern for dynamic styling and attribute updates.

Fork of Choropleth with Histogram Brushing

This interactive visualization displays the August 2016 unemployment rate for U.S. counties on a choropleth map, using a quantile color scale with d3.scaleQuantile and the Inferno interpolator. A brushable histogram below the map, built with d3.bin and d3.brushX, allows filtering highlighted counties by rate, with non-selected areas grayed out via d3-rosetta utilities. The map supports zooming, uses topojson-client for county boundaries, and renders with d3.geoPath and the geo-albers-usa-territories projection.

Choropleth with Histogram Brushing

This interactive data visualization displays the unemployment rate by U.S. county for August 2016. A choropleth map uses a quantile color scale with four bins, rendered via `d3.geoPath` and the `geo-albers-usa-territories` projection. A linked histogram below the map, built with `d3.bin` and `d3.brushX`, allows users to brush a range of values, which highlights matching counties on the map while dimming others. The visualization also supports zooming through the `d3.zoom` utility, with map rendering optimized using memoization.

Choropleth

This choropleth maps U.S. county-level unemployment rates from 2008, encoding values with a d3.scaleQuantize that bins rates from 0 to 15% into nine color classes. Rendered with SVG, the map uses a white state boundary overlay to delineate county borders, while the quantized color scale (from light blue to dark navy) visually distinguishes unemployment ranges. The visualization is built with D3 v4 and TopoJSON, and it includes a resize handler to scale the map responsively.

County Choropleth

This visualization is a county-level choropleth map of the unemployment rate across the United States, using data from August 2016. The map is rendered with an Albers equal-area projection that includes all US territories, drawing county boundaries with `d3.geoPath` and colored using a quantile scale with the Inferno color palette via `d3.scaleQuantile` and `d3.interpolateInferno`. Counties with missing data appear red, while state boundaries are stroked in white. The implementation uses `d3.select` and `.join` for idempotent rendering, with `getUSAtlasData` fetching GeoJSON from the `us-atlas` package and `d3.json` for data loading.

Choropleth map

This choropleth map displays U.S. county-level unemployment rates as of August 2016, using a threshold scale with a blue sequential color scheme. The map is rendered as SVG with `d3.geoPath` and TopoJSON data from the Census Bureau and the Bureau of Labor Statistics. A legend with a linear axis shows the percentage ranges, and hovering over a county reveals its exact rate via a tooltip. The code also demonstrates preprocessing the raw fixed-width text data into a TSV using command-line utilities like `dsv2dsv`.

Fork of Choropleth with Histogram Brushing

This fork of the D3 Choropleth example visualizes U.S. county unemployment rates from August 2016, with a brushable histogram below the map that filters highlighted counties. Brushing the histogram dims counties outside the selected rate range using a quantile color scale interpolated with d3.interpolateInferno. The map uses d3.geoPath with geoAlbersUsaTerritories projection and topojson-client for county boundaries. The implementation leverages d3-rosetta’s memoization helpers and d3.brushX for interactive filtering, with zoom support via d3.zoom.

d3 chorplath map

This choropleth map of the United States displays county-level unemployment rates using a quantized color scale. The visualization renders counties as SVG paths, colored from light to dark blues based on rates from 0 to 15 percent, with state boundaries overlaid in white. Built with D3 v3, it uses `d3.geo.albersUsa` and `d3.geo.path` for projection, TopoJSON for US county and state geodata, and a queue to load JSON and TSV data asynchronously.
