Forked from Choropleth Map

This choropleth map colors countries by their economy grouping, using a spectral color scale assigned through D3's `scaleOrdinal` and `schemeSpectral`. The code projects geographic features with `geoNaturalEarth1` and `geoPath` onto an SVG, overlaying a white legend built by a custom `colorLegend` component. Hovering highlights a country in red via CSS. Data comes from the `world-atlas` package, merging TopoJSON shapes with TSV metadata. Zoom interactions are handled through D3's `zoom` event, transforming the map group.

Choropleth Map

This choropleth map colors countries by their economy type using a categorical color scale, with a legend showing each category. It renders world geography as SVG paths via `d3.geoPath` and the Natural Earth projection, while `d3.zoom` enables panning and zooming. The code loads TopoJSON and TSV data from the world-atlas package, mapping country IDs to economy labels, and uses `d3.scaleOrdinal` with `schemeSpectral`. Hovering highlights a country in red.

Choropleth Map

This choropleth map colors world countries by their economy category using an ordinal color scale with a spectral scheme, and displays a color legend with clickable circles. It renders geographic boundaries with antialiased SVG paths via `d3.geoPath` and the Natural Earth projection, while loading data from the world-atlas package (TSV metadata and TopoJSON geometries) and processing it with `topojson.feature`. Hovering highlights a country in red, and the map supports zooming through the `d3.zoom` interaction.

Choropleth Map

A choropleth map colors countries by their economy type, using a spectral color scale assigned through d3.scaleOrdinal. The map is drawn with d3.geoPath and the Natural Earth projection, while data is loaded asynchronously from World Atlas TSV and TopoJSON files. Hovering highlights countries in red, and a custom legend displays the color categories. The visualization supports zooming via d3.zoom, with zoom state handled through event transforms.

Choropleth Map

This choropleth map colors countries by their economy category using a sequential spectral color scale. It renders world geography as SVG paths via the `d3.geoPath` and `d3.geoNaturalEarth1` projection, with zoom support through `d3.zoom`. Country names and values appear as tooltips, and a custom `colorLegend` component displays the ordinal scale. The data is loaded from a TopoJSON world atlas and a TSV mapping country IDs to metadata. Hovering highlights countries in red.

Choropleth Map

This choropleth map colors countries by their economy classification, using a sequential spectral color scale to distinguish categories. The visualization renders geographic boundaries with `d3.geoPath`, projecting the world using the Natural Earth projection and enabling zoom and pan through `d3.zoom`. The code loads world topology from TopoJSON and joins it with TSV metadata via `d3.tsv`, while a custom color legend component displays the categorical scale. Hovering highlights individual countries in red, and the map includes data from the world-atlas dataset.

Choropleth Map

This choropleth map visualizes world economies by coloring each country according to its economic classification, using a spectral color scale created with `d3.scaleOrdinal` and `schemeSpectral`. The map renders as an SVG using `d3.geoPath` with the Natural Earth projection, displaying country data loaded from the world-atlas TopoJSON and TSV files. Interactive zooming via the `zoom` event lets users explore regions, while a custom `colorLegend` function shows the categorical color assignments.

Choropleth Map

This choropleth map colors world countries according to their economy group, using a spectral color scale to differentiate categories. It renders geographic boundaries with d3.geoNaturalEarth1 and d3.geoPath, and includes an interactive color legend built with custom SVG components. Users can pan and zoom the map via d3.zoom, while tooltips reveal country names and economy values. The visualization loads TopoJSON data from the world-atlas package and joins it with TSV metadata to assign colors, with hover states highlighted in red.

Choropleth Map

This choropleth map colors countries by their economy classification using an ordinal color scale derived from d3.scaleOrdinal and d3.schemeSpectral. It renders world geography with d3.geoPath and a Natural Earth projection, with zoom and pan via d3.zoom. A color legend built from d3.zoom and custom SVG circles and text displays the categorical levels. The data comes from a GitHub-hosted CSV joined to TopoJSON world atlas geometries using topojson.feature. Hovering highlights individual countries with a red fill.
