This map visualizes world countries with a choropleth encoding of randomly generated dummy data values. The visualization uses a Natural Earth projection, with countries colored on a sequential blue interpolator and orange highlighting on hover. It loads GeoJSON country boundaries from the world-atlas TopoJSON dataset via `topojson.feature`, then renders them as SVG paths using `d3.geoPath`. A floating tooltip, positioned on mousemove, displays each country’s numeric value as the user interacts.

Map

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.

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.

MAP

A map of world countries renders as SVG paths, with each country colored white and outlined in dark grey, while oceans appear light blue. Hovering a country turns it light blue. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere and country boundaries from the world-atlas TopoJSON dataset, with `topojson.feature` converting the raw data into features. Zooming is enabled via D3’s `zoom` behavior, which applies transforms to the map group.

Map.js!

This map visualization displays the world’s countries by using a Mercator projection to render geographic features as filled SVG paths on a light gray sphere background. The code loads country boundaries from the world-atlas TopoJSON dataset and converts them to GeoJSON with `topojson.feature`, then draws each country using `d3.geoPath`. Styling applies a blue fill with dark strokes and a subtle opacity, while the hidden overflow and full-bleed body create an immersive, full-window presentation.

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 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 in green with a dark blue ocean sphere, highlighting each country in red on hover. Using D3 v5 and TopoJSON, it loads world-atlas data (50m resolution) to generate SVG paths via `d3.geoPath` with a `geoNaturalEarth1` projection, matching ISO country IDs to names from a TSV table. The map supports zoom and pan interactions through `d3.zoom`.

Map

This example displays a static world map rendered as light blue countries with white borders on a white background. The visualization loads geographic data from the world-atlas TopoJSON dataset and converts it into GeoJSON features using the topojson-client library. D3’s geoSpatial projection, `d3.geoNaturalEarth1`, and the `d3.geoPath` generator draw each country as an SVG path element. All map rendering occurs within an SVG container, with styling applied via a CSS class.
