A choropleth map colors world countries by income group using a natural Earth projection, with a color legend and zoom interaction. It uses `d3.geoNaturalEarth1` and `d3.geoPath` to render the GeoJSON features, while `d3.scaleOrdinal` and `schemeReds` map categorical values to colors. The legend updates with a transition, and data comes from World Atlas TopoJSON and TSV files. Hovering highlights countries, and mouse-wheel zoom is supported via `d3.zoom`.

D3 Course Code Along - Choropleth Map

This choropleth map displays world countries colored by income group, with a legend showing the ordinal color scale. Built with D3 v5, it uses `d3.geoMercator` for projection, `d3.geoPath` to render geographic features from TopoJSON world-atlas data, and `d3.scaleOrdinal` with `schemeReds` for color encoding. Interactive zooming is enabled via `d3.zoom`. A custom color legend with animated circles transitions updates smoothly, and hover effects highlight individual countries.

D3 Course Code Along - Choropleth Map

This choropleth map colors world countries by income group, using a red sequential color scale with a natural Earth projection. The visualization includes interactive zooming and panning, plus hover effects that highlight individual countries on mouseover. Built with D3 v5, it loads TopoJSON country boundaries from the World Atlas and TSV metadata to join income classifications to each country. Animated color legend transitions update dynamically, while the globe outline is rendered using d3.geoPath with a sphere geometry.

D3 Course Code Along - Choropleth Map

This choropleth map visualizes global income groups using a natural Earth projection, with countries colored according to their income classification. The map is rendered as SVG paths generated by `d3.geoPath` from TopoJSON data loaded from World Atlas, combined with TSV metadata. A custom color legend displays the ordinal color scale using `d3.scaleOrdinal` with reds, and a zoom interaction allows viewers to pan and scale the map. Animated transitions with `transition.duration` update the legend circles when the data domain changes.

Fork of D3 Course Code Along - Choropleth Map

A world choropleth map colors each country by its income group, using a sequential red color scale derived from World Bank data. The visualization renders with D3 v7 and the `geoNaturalEarth1` projection, building paths via `geoPath` and TopoJSON country geometries. A custom color legend animates its circles with a `transition` to reflect scale changes, while a zoom behavior lets users pan and scale the map. Country names appear as tooltips on hover, drawn from the accompanying TSV metadata.

Fork of D3 Course Code Along - Choropleth Map

A choropleth map of world countries colored by income group, rendered with a Natural Earth projection. The visualization loads world-atlas TopoJSON data via `d3.json`, projects it with `d3.geoPath`, and colors each country using a sequential red scheme from `d3.schemeReds` based on a categorical `d3.scaleOrdinal` scale. An interactive legend built with custom SVG `circle` and `text` elements shows the color categories. The map supports zooming via `d3.zoom` and includes hover effects that highlight countries.

Fork of D3 Course Code Along - Choropleth Map

This interactive choropleth map colors countries by income group, with a color legend that animates its circles and uses sequential reds from d3.scaleOrdinal. Built with d3.v5 and topojson, it projects world atlas data using d3.geoNaturalEarth1 and renders countries as SVG paths via d3.geoPath. A zoom tool from d3.zoom is applied, and hover effects highlight individual countries, while data is loaded from unpkg-hosted TSV and TopoJSON files.

D3 Course Code Along - Choropleth Map with Clickable Legend

This choropleth map colors countries by income group using a categorical color scale. A clickable legend filters the map, dimming unselected categories to 10% opacity while highlighting the chosen group. Built with D3 v5, it uses d3.geoPath with a d3.geoNaturalEarth1 projection to render country boundaries from TopoJSON data. The visualization also incorporates d3.zoom for interactive panning and zooming, and animates the legend’s color transitions with d3.transition.

Fork of D3 Course Code Along - Choropleth Map

This choropleth map visualizes world population data by country income group, using color intensity to show distribution across regions. The visualization supports interactive zooming and panning, with hover effects highlighting individual countries. Built with D3 v5, it uses `geoNaturalEarth1` projection, `geoPath`, and `geoMercator` for map rendering, while `scaleOrdinal` with `schemeReds` maps income categories to colors. A dynamic color legend animates its circles using transitions. Country boundaries and income classifications come from the World Atlas TopoJSON dataset, with a hover tooltip displaying country names.
