world map

D3 map

This example visualizes a world map with animated location markers derived from a SPARQL query against the Network Digital Heritage dataset. The map uses a natural Earth projection, with countries rendered as SVG paths via `d3.geoPath` and `topojson.feature`. Each data point is plotted as a circle whose radius transitions from 10px to 8px using a staggered delay and `d3.easeBounce`, creating a popping effect. The code loads world geometry from a TopoJSON file and fetches JSON results, converting latitude and longitude values before projecting them.

World Map

This example renders a world map using a Natural Earth projection, displaying country boundaries as green shapes on a light blue sphere. The visualization uses d3.geoNaturalEarth1 for the projection and d3.geoPath to generate SVG paths from GeoJSON data converted from TopoJSON via the topojson.feature API. World country data is loaded from the world-atlas package, and the SVG includes a sphere outline to emphasize the spherical projection. The map is static, with no interactive elements or animations.

world map

This example renders a world map using the Natural Earth projection, displaying country boundaries as green SVG paths with yellow strokes on a green background. It fetches geographic data from the world-atlas TopoJSON dataset and converts it to GeoJSON features using the `feature` function from topojson. The visualization uses d3.geoPath with d3.geoNaturalEarth1 to project and draw the paths, while d3.json loads the remote dataset asynchronously before appending the country shapes to the SVG canvas.

D3 map

This example visualizes a world map with animated points representing geographic locations from a SPARQL query against the Network Digital Heritage dataset. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath` to render country boundaries from TopoJSON data. After fetching and parsing the query results, circles are appended to the SVG and animated with staggered `transition.attr` delays, using `d3.easeBounce` to grow each point from zero to its full radius. The rendering relies on SVG elements and the D3 v5 library, including `select`, `json`, and `feature` from TopoJSON.

world map

This example displays a natural Earth projection of the world, with landmasses rendered in green on a light blue spherical backdrop. It uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to generate SVG paths from TopoJSON data loaded from the world-atlas dataset. The code converts the TopoJSON country features to GeoJSON via the `feature` method from Topojson, then appends each path to the SVG. The sphere outline is drawn first to establish the globe’s boundary.

world map

This example displays a world map using natural Earth projection, with countries rendered as green filled paths with subtle black strokes against a blue spherical backdrop. It demonstrates loading TopoJSON country boundaries from the world-atlas package, converting them to GeoJSON via `topojson.feature`, and projecting them with `d3.geoNaturalEarth1` and `d3.geoPath`. The visualization also shows a sphere outline created from a GeoJSON Sphere object, all drawn as SVG elements using D3 v5’s selection and data-join methods.

Fork of D3 map

This visualization displays a natural Earth projection world map with animated green circles marking locations from a SPARQL query. The map and circles are rendered as SVG using `d3.geoPath` and `d3.geoNaturalEarth1`, with country outlines from TopoJSON. Location data comes from a Dutch heritage dataset, queried via SPARQL for coordinates and country labels. Each circle animates in with a staggered delay using `transition` and `d3.easeBounce`, growing from zero to its final size to reveal the distribution of points.

World Map

A world map rendered with D3.js and a Natural Earth projection displays country boundaries in light green over a blue sphere. The visualization uses `d3.geoNaturalEarth1` for the projection and `d3.geoPath` to generate SVG paths from TopoJSON data. Country shapes are drawn by fetching a remote world.json file via `d3.json`, then processing it with TopoJSON's `feature` method. The example demonstrates fundamental DOM manipulation by appending paths to SVG elements.
