This fork of a D3 v5 choropleth map displays global economic data from the world-atlas dataset, with countries colored by an ordinal spectral scale. Users can click items in the attached color legend to filter the map, dimming non-matching countries and highlighting selected ones. The code uses `d3.geoPath` with a natural Earth projection and `d3.scaleOrdinal` to map values to colors, while the legend’s click handler toggles the `selectedColorValue` to update opacity and stroke width. Hovering over countries also turns them red, with tooltips showing names and values.

AI-generated description

Fork of Choropleth Map with Interactive Filtering F

This choropleth map displays global country-level economic classifications using an ordinal color scale. Users can click legend items to highlight matching countries and dim all others, with a second click clearing the filter. The map uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` for pan/zoom interaction, with SVG rendering. Data comes from the world-atlas TopoJSON dataset, joined to TSV metadata. The legend and map are both rendered with D3 selections, and hover effects highlight individual countries.

Fork of Choropleth Map with Interactive Filtering

This choropleth map visualizes global economic classifications with an interactive color legend that filters countries by category. Clicking a legend item highlights matching countries while dimming others, and clicking again removes the filter. The map uses D3 v5 with `geoNaturalEarth1` projection, `geoPath`, and zoom behavior, while the legend leverages `scaleOrdinal` with `schemeSpectral` colors. Data comes from the World Atlas TopoJSON and TSV files, rendered as SVG with hover tooltips showing country names and values.

Fork of Fork of Choropleth Map with Interactive Filtering

This choropleth map displays global economic groups, color-coded through an ordinal spectral scale. Hovering over a legend item interactively filters the map, dimming all countries not belonging to that category and highlighting those that do. The visualization uses D3.js v5 with `geoNaturalEarth1` and `geoPath` for map projection, while `scaleOrdinal` and `schemeSpectral` drive the color encoding. Clicking legend entries toggles filtering by economic group, with world data sourced from the World Atlas TopoJSON and TSV files.

Fork of Choropleth Map with Interactive Filtering

This choropleth map displays world countries colored by economy type, with an interactive color legend that filters the map when clicked. Hovering over legend items dims non-matching countries, while selected countries are highlighted and the sphere fades to emphasize the filter. Built with d3.v5, it uses d3.geoNaturalEarth1, d3.geoPath, d3.scaleOrdinal, and d3.zoom for panning and zooming, rendering as SVG from TopoJSON world-atlas data.

Fork of Choropleth Map with Interactive Filtering

This choropleth map presents world countries colored by economic classification, with an interactive color legend that filters highlighted regions on click and hover. Users can zoom and pan the map, while clicking a legend category dims non-matching countries and re-clicking clears the filter. Built with D3 v5, it uses `d3.geoNaturalEarth1` and `d3.geoPath` for map projection, `d3.zoom` for navigation, and `d3.scaleOrdinal` with `schemeSpectral` for coloring. Data comes from the World Atlas TopoJSON and TSV files, rendered as SVG paths with tooltips.

Fork of Choropleth Map with Interactive Filtering

This interactive choropleth map displays the world’s countries colored by their economic classification, with a color legend that filters the map when clicked. Clicking a legend value highlights corresponding countries and dims all others; clicking again clears the filter. Hovering a country reveals its name and value in a tooltip. Built with D3 v5, it uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` to render country paths, and a custom `colorLegend` module for the clickable legend. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG.

Fork of Choropleth Map with Interactive Filtering

This choropleth map displays global economic data by country, with a color legend that doubles as an interactive filter. Users click legend items to highlight matching regions while dimming others. The map uses d3.geoNaturalEarth1 projection with d3.geoPath for rendering, and d3.zoom for panning. The legend employs scaleOrdinal with schemeSpectral colors, and onClick handlers toggle selection. Data comes from world-atlas TopoJSON and TSV files, processed via topojson.feature, with SVG output.

Fork of Choropleth Map with Interactive Filtering

This choropleth map visualizes world countries colored by economic classification, with an interactive color legend that filters the map when clicked. Hovering a country reveals its name and value via a tooltip, and the map supports zooming and panning. The visualization uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` for the map, while `scaleOrdinal` with `schemeSpectral` maps data values to colors. Data is loaded from the World Atlas TopoJSON and TSV files, and filtering updates both map and legend opacities in real time.
