Forked from HTML Starter

This example displays a world map colored by values joined from a CSV dataset, with a hover tooltip showing each country’s name and numeric value. It renders an SVG using D3 v7’s `d3.geoNaturalEarth1` projection and `d3.geoPath`, loading country boundaries from TopoJSON via `world-atlas`. Country colors are assigned through a sequential `d3.scaleSequential` interpolator, while the CSV is joined using a `Map`. The tooltip appears on mouseover events, positioned at the cursor.

Fork of Let's make a map with D3.js!

This map visualization displays world countries colored in light green on a blue sphere, with hover effects turning countries red. It uses D3 v5 and TopoJSON to load and render world geography from the world-atlas dataset. The code combines `d3.geoNaturalEarth1` for projection, `d3.geoPath` for drawing country boundaries, and `d3.zoom` for interactive panning and zooming. Country names are joined from a TSV file and shown as SVG `<title>` tooltips.

This choropleth map visualizes world population data from a CSV file, displaying countries in a sequential blue color scale based on their population size. It renders an SVG with D3 v6, using `d3.geoNaturalEarth1` and `d3.geoPath` to draw country boundaries from TopoJSON world-atlas data. Interactive tooltips appear on mousemove, showing country names and population values, while a gradient legend indicates the color scale up to 1.5 billion people.

Fork of World Map with D3.js!

This example displays an interactive world map where each country is rendered as a green SVG path with a black stroke. A blue sphere provides the background, and hovering over a country highlights it in orange. Built with D3.js v5 and TopoJSON, it uses `d3.geoPath` with `d3.geoEquirectangular` projection to draw the map from the world-atlas countries-110m.json data source. The SVG rendering is styled via CSS classes, with hover effects defined in the stylesheet.

Fork of World Map with D3.js!

This example displays a world map using a blue sphere as the globe background and green country polygons with black outlines. It uses d3.geoEquirectangular for the projection, d3.geoPath to generate SVG paths, and TopoJSON’s feature method to convert country boundaries from the world-atlas@2 dataset (countries-110m.json). Countries change color to dark orange on mouse hover, as defined by the CSS :hover rule. The SVG renders with a fixed 960×500 viewport, and the code loads d3 v5, TopoJSON v3, and a bundled index.js.

This example displays a choropleth map of the world, coloring countries by their sample population values using a sequential blue color scale. The map is rendered with SVG and D3.js’s `d3.geoMercator` projection and `d3.geoPath`. It loads real world geometry from a local GeoJSON file (`countries.geo.json`) and overlays tooltips via SVG `title` elements. Population data is provided as a static JavaScript object, with missing countries shown in gray.

Fork of Let's make a map with D3 with popup.js!

This is a D3.js map of the world created with a Natural Earth projection, using `d3.geoPath` and `d3.geoNaturalEarth1` to render country outlines. Each country is joined with a CSV dataset by its numerical ID, and hovering over a country triggers a custom tooltip via `d3.select` and DOM `mouseover` events, displaying the country's ID and its associated value from the CSV. The visualization demonstrates basic interaction and data-binding on an SVG canvas, with countries colored light blue and highlighting red on hover.

Fork of World Map with D3.js!

This example displays a world map as an SVG graphic, with each country rendered as a green path with black outlines. Hovering over a country changes its fill color to orange, providing basic user feedback. The visualization uses D3 v5 functions such as `select`, `json`, `geoPath`, and `geoEquirectangular` for the projection, while TopoJSON’s `feature` method converts the loaded world-atlas countries-110m.json data into GeoJSON features for rendering.
