Forked from Choropleth map

A choropleth map colors world countries according to their economic classification, with a color legend that filters and highlights selected categories. Users can click legend entries to dim non-matching countries and intensify the selected region. Built with D3.js, the visualization uses `d3.geoNaturalEarth1` and `d3.geoPath` to project TopoJSON data from the world-atlas package, while `d3.scaleOrdinal` with `d3.schemeSpectral` assigns colors. Interactive zoom via `d3.zoom` and SVG rendering provide the map interface.

Choropleth Map

This choropleth map colors world countries by economic classification, using a spectral color scale to distinguish categories. Clicking a legend item filters the map to highlight only matching countries, while zooming and panning are enabled via d3.zoom. The visualization imports world-atlas TopoJSON and TSV data, projecting features with d3.geoNaturalEarth1 and d3.geoPath. Map and legend are rendered as SVG, with hover states and opacity dimming for non-selected regions.

Choropleth Map

This choropleth map colors world countries by economic classification using a categorical ordinal scale with a spectral color scheme. Users can zoom and pan the natural Earth projection, while a custom color legend displays the category colors and labels. The visualization loads geographic and metadata from the world-atlas TopoJSON and TSV files, rendering paths via d3.geoPath and enabling interaction through d3.zoom. Hovering highlights individual countries, and the legend is built with reusable d3 selections.

Choropleth Map

A choropleth map colors countries by economic category using an ordinal color scale with a spectral palette. The visualization loads world geometry and country metadata from the world-atlas TopoJSON and TSV files, rendering paths with `d3.geoPath` and a Natural Earth projection. Users can pan and zoom via `d3.zoom`, while a custom legend built with D3 selections displays color categories as circles and text. Hovering highlights a country in red, and tooltips show each nation's name and economy type.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with the spectral scheme, sourced from the World Atlas TopoJSON dataset. The map supports interactive zooming and panning, and clicking a legend item highlights matching countries while dimming others. It is built with D3 v5, using `d3.geoNaturalEarth1` and `d3.geoPath` for geographic projections, and `d3.zoom` for navigation, with all elements rendered as SVG.

Choropleth Map

A choropleth map colors countries by economic income group using an ordinal color scale. The visualization uses D3 v5 with d3.geoPath and a Natural Earth projection to render TopoJSON world data loaded from the world-atlas package. Users can zoom and pan via d3.zoom, and hovering highlights individual countries. A custom color legend component displays the category colors and labels, with interactivity handled through SVG selections.

Choropleth Map

This choropleth map colors countries by economic classification using an ordinal color scale with a spectral scheme. Hovering highlights a country in red, and the map includes a legend showing color categories. Built with D3 v5, it uses `geoPath` with the Natural Earth projection and loads geographic data from the world-atlas TopoJSON and TSV files. The visualization supports zooming via D3's zoom event and renders as an SVG.

Choropleth Map

This choropleth map visualizes the world's countries, colored according to their economic classification. The map uses D3's `geoNaturalEarth1` projection and `geoPath` to render the geographic shapes, with an ordinal color scale based on a spectral scheme to represent the data. Country data comes from the world-atlas dataset, which merges TopoJSON geometry with TSV metadata. Interactive features include zooming via `zoom()` and a color legend built with `scaleOrdinal` and SVG elements. Hovering over a country highlights it in red and displays a tooltip with its name and economic group.

Choropleth Map

This choropleth map visualizes countries’ economic classifications using a color scale based on the world-atlas TopoJSON dataset. The map renders with d3.geoPath and a natural Earth projection, while a d3.scaleOrdinal with schemeSpectral colors fills each country. Hovering highlights countries in pink, and a color legend explains the ordinal scale. Users can zoom and pan via d3.zoom, with all interaction and styling implemented in SVG.
