Choropleth map interactive filtering

This interactive choropleth map displays world countries colored by economic classification, with a legend that filters the map by clicking a category. Users can zoom and pan the map, and selected countries are highlighted while unselected ones fade. The visualization uses D3 v5 APIs including `d3.geoNaturalEarth1`, `d3.geoPath`, `d3.zoom`, and `d3.scaleOrdinal`, rendering with SVG. Data comes from the World Atlas TopoJSON file merged with TSV metadata.

Interactive choropleth map filtering

An interactive choropleth map displays global economic classifications using color-coded countries over a natural Earth projection. Clicking legend entries filters the map, dimming unselected economies and highlighting the chosen one while allowing zoom and pan through d3.zoom. The visualization uses d3.geoPath to render TopoJSON world-atlas data, d3.scaleOrdinal with schemeSpectral for color mapping, and SVG elements with transitions managed by D3’s data join. Hovering changes country fill to red, and tooltips show country names and values.

Choropleth Map with Interactive Filtering

This choropleth map displays country-level economic classifications using a color scale based on world-atlas TopoJSON data. Users can click legend items to highlight countries matching that category while dimming others, and hover effects further emphasize individual countries. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.zoom for panning and zooming, and d3.scaleOrdinal with schemeSpectral for color encoding. The legend and map are built as separate SVG components that re-render when the selection changes.

Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive color legend that filters the map when clicked. Hovering reveals country names and values via tooltips, while non-selected countries and legend items fade to low opacity. The visualization uses d3.geoNaturalEarth1 with d3.geoPath for projected SVG rendering, d3.scaleOrdinal with schemeSpectral for color mapping, and d3.zoom for panning. Data comes from the world-atlas TopoJSON and TSV files, processed through topojson.feature. Clicking a legend item toggles filtering on that value.

Choropleth Map with Interactive Filtering

This choropleth map colors countries by economic classification using a spectral color scale, with an interactive legend that filters map regions by clicking legend items. The visualization combines a world map rendered with d3.geoPath and d3.geoNaturalEarth1, a colorLegend with clickable circles, and d3.zoom for panning and zooming. Country data comes from the world-atlas TopoJSON and TSV datasets, with hover highlighting and tooltips showing country names and values.

An interactive choropleth map colors world countries by economic classification using d3.geoNaturalEarth1 and d3.geoPath, with a clickable ordinal color legend to filter highlighted regions. Built with D3 v5 and TopoJSON world-atlas data, it supports zooming via d3.zoom and renders as SVG. Hovering dims non-selected countries while selected ones gain emphasis.

Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economic classification, with an interactive color legend that filters which countries remain highlighted. Clicking a legend item dims all countries not in that category, while clicking the same item again clears the filter. The visualization uses d3.geoNaturalEarth1 for projection, d3.geoPath for rendering SVG paths, d3.scaleOrdinal with a spectral scheme for coloring, and d3.zoom for pan and zoom. Data comes from the world-atlas TopoJSON and TSV datasets, loaded via d3.json and d3.tsv.
