Fork of Choropleth with Multidimensional Filtering

This interactive visualization links a choropleth map of U.S. county unemployment rates from the BLS with a brushed histogram of the same metric. Brushing the histogram filters the map, dimming counties outside the selected range while highlighting those within it. Users can hover over counties to see their exact values. The implementation uses d3.geoPath with a geoAlbersUsaTerritories projection, d3.scaleQuantile with an inferno color scale, and d3.brushX for the histogram’s interactive interval selection. Data comes from a JSON dataset of unemployment rates for August 2016.

AI-generated description

A rough PoC for multiple histograms linked to a choropleth map. Shows two metrics:

  • Unemployment rate by U.S. county, August 2016 from the BLS.
  • Educational attainment ("Percent of adults with a bachelor's degree or higher, 2018-22") from USDA Educational Attainment Dataset

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.

Choropleth with Multidimensional Filtering

A choropleth map of unemployment rates by U.S. county is linked to two interactive histograms, one for unemployment and one for educational attainment. Brushing a histogram filters the map to highlight counties within the selected range, while hovering over a county reveals its values in both histograms. The visualization uses D3’s `geoPath`, `scaleQuantile`, and `brushX` with data from the BLS and USDA.

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.

Fork of Choropleth with Histogram Brushing

This visualization shows the unemployment rate for U.S. counties in 2022 using a choropleth map paired with a brushable histogram. The map colors each county by quantile, while brushing a range on the histogram highlights matching counties and dims others. Built with vanilla JavaScript and D3, it uses `d3.geoPath` for map rendering from `us-atlas` TopoJSON data and `d3.scaleQuantile` for color mapping, with zooming via `d3-rosetta`.

Fork of Choropleth with Histogram Brushing

This example visualizes August 2016 unemployment rates across U.S. counties, combining a choropleth map with a brushable histogram. Users can brush the histogram to filter the map, highlighting only counties whose rates fall within the selected interval while dimming others. The map uses `geoAlbersUsaTerritories` projection with `d3.geoPath`, and the color scale is a quantile scale with four custom colors. Brushing is implemented via `d3.brushX`, and the code leverages `d3-rosetta` for DOM manipulation and zooming, with data from the `@oabouhas/unemployment` package.

Bivariate Choropleth with Histograms

This interactive visualization combines a bivariate choropleth map of U.S. counties with coordinated histograms to explore the relationship between unemployment rates and education levels. Using d3.geoPath with a TopoJSON atlas, the map colors each county by a 3x3 bivariate color scale, while brushing on either histogram filters the map and highlights counties in the selected range. Hovering over a county reveals its name in a label and marks its position in both histograms with vertical indicator lines. The visualization uses d3.brushX, d3.scaleQuantile, and smooth transitions to animate state changes between the coordinated views.

Map

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.
