This choropleth map visualizes country-level scalar data using color-coding over a geographical projection. Built with D3.js, it renders SVG paths from TopoJSON world data, with the projection handled by `d3.geoPath` and `d3.geoNaturalEarth1`. The map assigns colors based on a `scalerank` attribute using a `d3.scaleOrdinal` color scale, while a supplementary color legend displays the mapping. Interactivity is included via a zoom feature, and hovering over a country highlights it and displays a tooltip with its name and value.

Choropleth Map

A choropleth map uses color to encode values across world countries. D3’s `geoPath` and `geoNaturalEarth1` projection render the map from TopoJSON data, while a TSV file supplies per-country attributes. The map color-fills each country by its `scalerank` value using an ordinal color scale. A separate legend component displays the color-to-value mapping, and zooming is enabled via the `zoom` event.

Choropleth Map

This choropleth map visualizes world countries using a natural Earth projection, with color encoding driven by data loaded from the world-atlas TopoJSON and TSV files. The SVG rendering uses `d3.geoNaturalEarth1` and `d3.geoPath` to draw geographic features, while an ordinal color scale maps country attributes to fill colors. Interactive pan and zoom are enabled through `d3.zoom`, which transforms both the map and sphere layers. A color legend is positioned on the left side to interpret the scale.

Choropleth Map

A choropleth map displays countries of the world colored in light green, with a blue sphere representing the globe and black borders between nations. The visualization uses `d3.geoNaturalEarth1` projection and `d3.geoPath` to render geographic features from TopoJSON data, while country names come from tab-separated values (TSV) data. Interactive zooming is implemented with `d3.zoom`, converting events to SVG transforms. Hovering over a country changes its fill color to red through CSS `:hover` styles, and tooltips with country names appear via SVG `title` elements.

Choropleth Map

A choropleth map colors countries by economic grouping, with a legend of colored circles and a natural Earth projection. It uses d3.geoPath, d3.geoNaturalEarth1, d3.scaleOrdinal with schemeSpectral, and d3.zoom for panning. The code loads world atlas TopoJSON and TSV data via topojson.feature, rendering country paths as SVG with hover highlighting.

Choropleth Map

This choropleth map displays world countries using a natural Earth projection, with country boundaries rendered as interactive SVG paths. The visualization uses D3 v6 and TopoJSON to load and convert world-atlas data from unpkg, employing `d3.geoNaturalEarth1` and `d3.geoPath` for projection and path generation. Hovering over a country changes its fill from green to red, while a zoom behavior (`d3.zoom`) allows panning and scaling the entire map. The sphere background is filled blue, and country names appear as tooltips via SVG title elements.

choropleth map

A world map rendered as a choropleth uses color to encode each country’s economy classification. Built with D3 v5 and topojson, the visualization loads geographic data from a 50m world-atlas JSON and TSV files, then projects it using `geoNaturalEarth1`. The `scaleOrdinal` color scale applies the `schemeSpectral` palette, while a custom legend displays the categories. Hovering turns a country red, and zooming is supported via the `zoom` event handler.

Choropleth Map

This choropleth map visualizes countries colored by their economic classification, using a spectral color scale to distinguish categories. The map renders geographic boundaries as SVG paths via `d3.geoPath` and a Natural Earth projection. Data is loaded from the World Atlas TopoJSON and TSV files, merged by country ID, then assigned to the `d3.scaleOrdinal` color scale. A custom legend shows color swatches with labels, and hovering highlights individual countries in red. Interaction includes zoom and pan through the `d3.zoom` event, which applies an SVG transform.

Choropleth Map

This choropleth map visualizes countries colored by income group using a natural Earth projection. It loads world geometry from TopoJSON and joins it with TSV metadata via d3.json and d3.tsv, then renders paths with d3.geoPath. A d3.scaleOrdinal with a schemeSpectral range assigns colors, and an interactive legend built with d3-selection shows the categorical scale. The map supports zooming through d3.zoom and highlights countries on hover via CSS.
