Choropleth Map with Interactive Filtering

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to distinguish categories, with an interactive legend enabling users to click a category and highlight matching countries while dimming the rest. Built with D3 v5, the visualization uses `geoNaturalEarth1` and `geoPath` for map projection, `scaleOrdinal` and `schemeSpectral` for coloring, and `zoom` for panning. Data comes from the World Atlas TopoJSON and TSV files. Hovering reveals country names and values via SVG `title` elements.

Choropleth Map With Interactive Filtering

A choropleth map of world countries colored by economy, with an interactive color legend that filters the map to highlight countries in a selected category. Clicking a legend entry dims non-matching countries and increases their stroke width; clicking again clears the filter. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to render topojson country features from the world-atlas dataset, with `d3.scaleOrdinal` and `schemeSpectral` for colors.

Choropleth Map with Interactive Filtering

A world choropleth map colors countries by economic classification using a categorical ordinal scale. Clicking a legend item filters the map, dimming unselected countries and highlighting the chosen category while clicking again resets the view. The visualization is built with D3 v5, using `geoNaturalEarth1` and `geoPath` for map projection and rendering, with pan and zoom enabled via `d3.zoom`. Data comes from the World Atlas TopoJSON, and the legend uses SVG circles with click handlers.

Choropleth Map with Interactive Filtering

A choropleth map displays global economic classifications by country, with a color legend encoding each category. Clicking a legend item filters the map, dimming non-matching countries while highlighting the selected group. Hovering reveals country names and values via tooltips. Built with D3 v5, it uses `geoNaturalEarth1` and `geoPath` for SVG map rendering, `scaleOrdinal` with `schemeSpectral` for colors, and `zoom` for panning. Data comes from TopoJSON world-atlas merged with TSV metadata.

Choropleth Map with Interactive Filtering

A choropleth map colors countries by economic classification using a spectral color scale, with an interactive legend that filters the map when clicked. Hovering over a legend item dims all countries except those matching the selected category, while clicking toggles the filter on and off. Built with D3 v5, the visualization uses `d3.geoNaturalEarth1` for projection, `d3.geoPath` for rendering SVG paths, and `d3.zoom` for panning and zooming. Geographic data comes from the World Atlas TopoJSON dataset, with country names and economic groups loaded from a TSV file.

Choropleth Map with Interactive Filtering

A choropleth map displays world countries colored by their economy category, which can be interactively filtered by clicking entries in an adjacent color legend. The map renders geographic boundaries using `d3.geoPath` with a `geoNaturalEarth1` projection, and supports panning and zooming through `d3.zoom`. Clicking a legend item, built with `d3.scaleOrdinal` and `schemeSpectral`, dims non-matching countries while highlighting the selected group. The data comes from the world-atlas TopoJSON and TSV files, with the visualization built using D3 v5 and SVG.

Choropleth Map with Interactive Filtering

This choropleth map displays countries colored by economic grouping, with an interactive color legend that filters the map when clicked. Users can select a specific economic category to highlight those countries and dim all others, or click again to reset the view. Pan and zoom controls allow exploration of the global map. The visualization is built with D3 v5, using `d3.geoPath` and `d3.geoNaturalEarth1` for map projection, plus `d3.scaleOrdinal` and `d3.schemeSpectral` for color encoding. Country boundaries and metadata come from the world-atlas TopoJSON and TSV datasets.

Choropleth Map with Interactive Filtering

A choropleth map displays countries colored by economy group using an ordinal color scale, with a sidebar legend of clickable swatches. Clicking a legend item filters the map to highlight only countries in that category, dimming non-matching regions and adjusting opacity. The visualization uses D3 v5’s `geoPath`, `geoNaturalEarth1`, `scaleOrdinal`, and `schemeSpectral` for cartographic rendering and coloring, while the legend handles events via `on('click')`. Country data merges TopoJSON geometry with TSV attributes from the world-atlas package.
