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 Assignment

This example shows an interactive world map where each country is rendered as a filled path, and hovering over a country turns it red. The map uses a natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with country boundaries loaded from TopoJSON data in the world-atlas package. Zoom and pan interactions are implemented using `d3.zoom`, which applies a transform to the map group. Country names are matched from ISO codes in a TSV file and displayed as tooltips using SVG `<title>` elements.

Map Interactions

This example displays an interactive world map using a natural Earth projection, with countries rendered as light green SVG paths that turn teal on hover. The visualization combines world-atlas TopoJSON data with a TSV file containing country names, which are added as native SVG `<title>` tooltips. The map supports pan and zoom through d3.zoom, while d3.geoPath and d3.geoNaturalEarth1 handle geographic projections. Hover effects use CSS pseudo-classes, and the map includes a blue sphere background for context.

Map Interaction

This example displays an interactive world map, rendering country boundaries as SVG paths using d3.geoPath and a d3.geoNaturalEarth1 projection. The map is built from TopoJSON data loaded via d3.json and the topojson.feature API, with country names attached as SVG title elements. The visualization supports panning and zooming through d3.zoom, which applies a transform to the map group, and highlights individual countries by changing their fill color on hover using CSS.

world map interaction

This example presents an interactive world map built with D3.js v5, displaying country boundaries and names sourced from the world-atlas TopoJSON dataset. Users can zoom and pan the map using d3.zoom, with the transform applied to a group element. Countries are rendered as SVG paths via d3.geoPath and a natural Earth projection, with tooltips showing country names from the TSV file. Hovering highlights countries in red, while the ocean sphere uses a blue fill.

Let's make a map with D3.js!

This example shows an interactive orthographic world map built with D3.js, where hovering over any country highlights it in red and displays its name as a tooltip. The map renders as SVG using `d3.geoPath` and `d3.geoOrthographic` for the projection, with country boundaries drawn from TopoJSON data loaded from the world-atlas dataset. The visualization also supports zooming and panning through `d3.zoom`. Country names are matched to geometries using ISO numeric codes from a TSV file.

simple map interactions

This example shows an interactive world map rendered as SVG, where each country displays its name as a tooltip on hover and the entire map can be panned and zoomed. It uses D3 v5’s `geoNaturalEarth1` projection with `geoPath` to draw country boundaries from TopoJSON data loaded from the world-atlas package, and country names are matched from a TSV file via ISO numeric codes. The zoom behavior is implemented with `d3.zoom`, applying the current transform to a group element, while CSS hover styles highlight countries and a sky-blue sphere path forms the ocean background.

World Map Interaction

This example displays an interactive world map built with D3 v5 and TopoJSON, rendered as SVG. Users can pan and zoom the map using D3’s `zoom` behavior, which updates a group transform. The map draws countries from the world-atlas TopoJSON file using `geoPath` and the `geoNaturalEarth1` projection. Hovering over a country highlights it in red via the `:hover` CSS rule, while country names appear as tooltips using SVG `<title>` elements.
