Map animation with D3.js

Map Interaction

This example displays an interactive world map rendered with SVG using the d3-geo-projection library, specifically the geoNaturalEarth1 projection. Countries from the world-atlas TopoJSON dataset are drawn as paths with d3.geoPath, each featuring a tooltip showing the country name. The map supports pan and zoom through d3.zoom, which applies a transform to the map group on events. Hovering over a country changes its fill color to red via CSS, while the sphere background uses a distinct blue fill.

Map interaction with D3.js!

This example demonstrates an interactive world map built with D3.js v5, allowing users to pan and zoom via the `d3.zoom` API. It renders country boundaries as SVG paths using `d3.geoPath` with a `geoNaturalEarth1` projection, applied to TopoJSON data from the world-atlas package. Country names are matched from a TSV file and displayed as tooltips via SVG `<title>` elements. Hovering changes the fill color through CSS, while the sphere background is styled as dark blue.

Map Interaction with D3!

This example shows an interactive world map rendered with SVG paths, where hovering over a country reveals its name as a tooltip and the map supports zooming and panning. It uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw countries from TopoJSON data provided by the world-atlas package, with country names loaded from a TSV file. The zoom behavior is implemented via D3’s `zoom` API, transforming a group element on the `zoom` event.

Map Tutorial

This visualization presents an interactive world map using a Mercator projection, rendered as SVG paths with animated zooming capabilities. Built with D3 v7 alongside the d3-geo and topojson libraries, the map displays countries from the world-atlas 110m JSON dataset as black-filled paths with whitesmoke borders. When users click a country, the map smoothly transitions and scales to center on that region, using d3.geoPath projections and transition animations with cubic easing. Clicking the same country again resets the view to the full world map.

Choropleth Map with D3 and SVG Final

This interactive world map uses a stereographic projection to display countries colored by income group. Built with D3 v5 and rendered as SVG, it loads GeoJSON and TSV data from the world-atlas package. Users can pan and zoom the map, which features a color legend and tooltips showing country names and income classifications. The visualization relies on d3.geoStereographic, d3.geoPath, d3.scaleOrdinal, and d3.zoom APIs.

Map Interaction with D3.js

This example shows an interactive world map with zoom and pan capabilities, where hovering over a country highlights it in red. Built with React and rendered as SVG, it uses D3.js v5 with `d3.geoNaturalEarth1` projection and `d3.geoPath` to draw countries from TopoJSON data. A `d3.zoom` handler transforms the map group on user interactions, while `d3.tsv` loads country names from a World Atlas TSV file to populate tooltips. The map features a steel-blue ocean sphere and light-green landmasses.

Zoomable World Map

This example presents an interactive world map with natural Earth projection, rendered as SVG paths. Users can zoom and pan via d3.zoom, with the `event.transform` applied to the map group. Country boundaries are drawn using d3.geoPath from TopoJSON data loaded from world-atlas, shaded light green with dark blue oceans. Hovering highlights countries in red, and each country includes a tooltip title populated from TSV metadata with country names.

Interactive Map with d3.js

This example shows an interactive world map rendered as SVG, with countries colored dark gray on a light sphere and highlighted in red on hover. The visualization uses d3.geoEqualEarth projection with d3.geoPath to draw country boundaries from TopoJSON data, while country names are loaded from a TSV file and displayed as tooltips via SVG title elements. Pan and zoom are enabled through d3.zoom, with scale limits between 1x and 8x, and the map renders using the world-atlas dataset at 110m resolution.
