Forked from D3

This example visualizes world countries as a choropleth-style map, coloring each country green with white borders on a dark blue spherical backdrop. The map renders as SVG using D3.js with a Natural Earth projection via `d3.geoNaturalEarth1`, and country boundaries are generated through `d3.geoPath`. Geographic data loads from the world-atlas TopoJSON file (countries-110m.json), which is converted to GeoJSON using the `feature` function from the topojson library. Hovering a country changes its fill to red, and each country includes a title tooltip displaying its name.

Choropleth Map

This choropleth map visualizes world countries with a green fill and a blue sphere background, using a natural Earth projection rendered to SVG. It draws country boundaries and names from the world-atlas TopoJSON dataset, with each country’s name displayed as a tooltip. The map supports pan and zoom via d3.zoom, and hovering over a country turns it red. The code leverages d3.geoNaturalEarth1, d3.geoPath, and topojson.feature to generate the geographic paths.

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

This choropleth map displays world countries colored in light green against a blue sphere, with hover highlighting in red. It uses a natural Earth projection via `d3.geoPath` and `geoNaturalEarth1` to render country boundaries from TopoJSON data sourced from the world-atlas package, paired with a TSV file for country names. Pan and zoom interactions are enabled through `d3.zoom`, while tooltips show country names via SVG `title` elements.

Choropleth Map

This choropleth map visualizes world countries using a natural Earth projection, with each country filled in light green and outlined in black. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, using `d3.geoPath` and `geoNaturalEarth1` to project and render country boundaries. Countries are colored by their assigned fill, and hovering over a country turns it red, while a tooltip displays the country name. The map includes a blue sphere background and supports zoom interactions through D3’s zoom behavior.

Map with D3.js

This map visualization displays world countries on a natural Earth projection using D3.js and TopoJSON data from the world-atlas dataset. It renders an SVG sphere background and country paths filled with teal, which turn red on hover through CSS. The code employs D3 v6 features like `geoNaturalEarth1` and `geoPath` to project geographic coordinates, while `topojson.feature` extracts country boundaries from the loaded TopoJSON file. A tooltip showing each country’s name appears via appended `title` elements.

Choropleth Map

This example presents a choropleth map of world countries rendered as an SVG using D3 v5. It displays each country as a red-filled path on a blue sphere, with country names shown in tooltips on hover. The visualization uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for drawing, and `d3.zoom` for panning and zooming. Data loads from TopoJSON and TSV files via the world-atlas package, with `topojson.feature` processing geographic boundaries. Hover effects change fill color to red, while the base country color is also red, with black stroke outlines.

Map

This example displays a world map rendered as SVG paths, with countries filled in light green against a blue sphere representing the Earth. It uses the `geoNaturalEarth1` projection and `geoPath` from D3 v5 to generate the map geometry, while TopoJSON’s `feature` method extracts country boundaries from the world-atlas 110m dataset. The visualization highlights the geographic layout without interactive features, focusing on static rendering of global landmasses.

Map

This example displays a world map using a natural Earth projection, with countries shown as light green shapes against a dark blue sphere background. The visualization is rendered as SVG paths derived from TopoJSON data loaded from the world-atlas package, with each country’s boundaries drawn using D3’s geoPath and geoNaturalEarth1 projection. The code utilizes D3 v6 for data binding and selection, while TopoJSON’s feature function converts the encoded topology into GeoJSON features for rendering.
