Choropleth Map with interactive filtering!

Choropleth Map with Interactive Filtering

This choropleth map displays global economies using color-coded countries, with interactive filtering through a clickable color legend. Hovering over legend items dims non-matching countries, while clicking toggles filtering and highlights selected categories. The visualization uses d3.geoPath with a geoNaturalEarth1 projection for map rendering, d3.scaleOrdinal with schemeSpectral for coloring, and d3.zoom for panning. Data comes from TopoJSON world-atlas files, with country names and economy classifications merged from TSV metadata.

Choropleth Map with Interactive filtering

This choropleth map of world economies uses color to encode categorical economic data, with an interactive legend that filters which countries are highlighted. Clicking a legend value dims all countries not in that category while emphasizing those that match. The visualization is built with d3.geoPath and d3.geoNaturalEarth1 for map projections, d3.scaleOrdinal with schemeSpectral for coloring, and a custom colorLegend component with click handlers. Country data comes from World Atlas TopoJSON and TSV files, rendered as SVG paths.

Choropleth Map with Interactive Filtering

This choropleth map visualizes world economies by color-coding countries according to their economic classification. Users can click legend categories to filter the map, highlighting matching countries while dimming others; clicking again resets the filter. The map uses d3.geoNaturalEarth1 projection and d3.geoPath for rendering, while d3.scaleOrdinal with d3.schemeSpectral supplies the color scale. Data comes from the world-atlas dataset, loaded via d3.tsv and topojson.feature.

Choropleth Map with Interactive filtering

This choropleth map displays world economies using a color gradient, with an interactive legend that filters countries by economic category. Users can zoom and pan the map, and clicking a legend entry dims non-matching countries while highlighting the selected group. The visualization uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering SVG paths, and d3.zoom for navigation. Data comes from the world-atlas TopoJSON and TSV datasets, with unemployment type and population shown in tooltips. The color scale uses d3.schemeSpectral, and legend interactions are handled through d3 event listeners.

Choropleth Map with Interactive Filtering

A choropleth map of global economies uses color to encode each country’s economic group, with an interactive color legend that filters the map by clicking a category. Pan and zoom via d3.zoom reveal spatial patterns, while hovering shows country names and values through SVG titles. The visualization is built with d3.geoNaturalEarth1 and d3.geoPath, using ordinal color scaling with d3.scaleOrdinal and d3.schemeSpectral. Data comes from the world-atlas TopoJSON and TSV files, rendered as SVG paths, with the legend updating opacity to dim unselected countries.

Choropleth Map with Interactive Filtering

This choropleth map visualizes global economic classifications, with each country colored according to its economy category. Users can click items in the interactive color legend to filter the map, highlighting matching countries and dimming all others, while hovering over the legend reveals tooltips. The visualization uses d3.geoPath with a geoNaturalEarth1 projection to render the map from TopoJSON world data, and d3.scaleOrdinal with schemeSpectral to assign colors. Zoom and pan functionality are implemented via d3.zoom, and the legend filtering uses click handlers with opacity transitions.

Choropleth Map with Interactive Filtering

A choropleth map displays world economies by color, showing how countries group by income category. Users hover over color legend items to filter the map, which dims non-matching countries and highlights selected ones. The visualization uses D3 v5 APIs including `geoNaturalEarth1` and `geoPath` for map projection, `zoom` for panning, and `scaleOrdinal` with `schemeSpectral`. It loads geographic boundaries from TopoJSON and economic data from TSV in `loadAndProcessData`. Interactive legend clicks trigger opacity changes through `colorLegend`, with SVG rendering throughout.

Choropleth Map with Interactive Filtering

This choropleth map displays world economies by color, with an interactive legend that filters countries by economic category. Clicking a legend item dims non-matching countries while highlighting the selected group. The visualization uses d3.geoNaturalEarth1 projection with d3.geoPath to render TopoJSON data from the world-atlas package, while d3.scaleOrdinal with schemeSpectral assigns colors. Zoom and pan are enabled via d3.zoom, and clicking legend items toggles opacity and stroke styling through SVG attributes.
