This example shows an interactive world map that supports zooming and panning, with country names revealed on hover. It renders geographic data using D3’s `geoNaturalEarth1` projection and `geoPath` into SVG, with country boundaries from TopoJSON and names from a TSV file. The zoom behavior is implemented via `d3.zoom`, applying a transform to a group element. Hover effects increase stroke width via CSS, while `title` elements display each country’s name.

Cheap Tricks for Interaction

This example shows an interactive world map that uses zoom and pan gestures to explore countries, with hover highlighting and country names in tooltips. Clicking a country logs its ID to the console, while a viewport sphere frames the geographic projection. The visualization relies on `d3.zoom` for user-driven transformations, `d3.geoNaturalEarth1` and `d3.geoPath` for rendering TopoJSON features from world-atlas data, and SVG elements styled via CSS. Country names are joined from TSV data using a lookup table.

Cheap Tricks for Interaction

This example demonstrates interactive pan and zoom on a world map, with countries highlighted in red on hover and tooltips displaying country names via SVG `<title>` elements. It uses a natural Earth projection (`geoNaturalEarth1`) and renders geographic features with `d3.geoPath`. The map loads world-atlas TopoJSON data and merges it with TSV country names, while the zoom behavior is implemented through `d3.zoom` applied to an SVG group.

This example shows a zoomable and pannable world map with hover highlighting on individual countries. It renders geographic boundaries using `d3.geoPath` with a `geoNaturalEarth1` projection, drawing country shapes from TopoJSON data and matching country names from a TSV file. The map supports interactive zooming through D3's `zoom` behavior, which applies transformations to the SVG group element. Country polygons fill with steel blue, and hovering changes their fill to light blue via CSS.

Cheap Tricks for Interaction

This example shows an interactive world map with zoom and pan capabilities, displaying country boundaries and names using natural Earth projection. The user can explore the map by dragging to pan and scrolling to zoom, which is implemented through d3.zoom. Countries are rendered as SVG paths using d3.geoPath, with hover effects highlighting regions in red. The visualization uses TopoJSON data from world-atlas and TSV country names, combining d3.json and d3.tsv for data loading within a Promise.all.

Cheap Tricks for Interaction

This example demonstrates interactive pan and zoom on a natural Earth projection map of world countries. Built with D3 v5, it uses `d3.zoom` to apply SVG transforms and `d3.geoPath` with `geoNaturalEarth1` for rendering. Country boundaries come from TopoJSON world-atlas data, with names matched via a TSV file and displayed as `<title>` tooltips. Hovering highlights a country in red, while the sphere background is blue.

Cheap Tricks for Interaction

This example shows an interactive world map rendered with SVG, where hovering over a country highlights it in red and zooming is enabled through mouse or touch gestures. The visualization uses D3 v5’s `d3.zoom` to apply a transform to a group element, while countries are drawn using `d3.geoPath` with a natural Earth projection. Geographic data comes from the world-atlas TopoJSON and TSV files, which supply country boundaries and names for tooltips.

Cheap Tricks for Interaction

This example demonstrates a zoomable world map with hover interactions, where countries change color on mouseover. It renders geographic features using d3.geoPath with a d3.geoNaturalEarth1 projection, and applies zoom behavior via d3.zoom to transform the map group. The map data comes from a TopoJSON file combined with a TSV file for country names, loaded through d3.json and d3.tsv. The SVG is styled with CSS for the country fills and hover effects.

Cheap Tricks for Interaction

This example shows an interactive world map with zooming and panning controlled by the mouse. Hovering a country turns it red, and a tooltip displays the country’s name. Built with D3 v5, it uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` to generate the country shapes, and the `zoom` behavior from the `d3` module to apply transforms on a zoom event. The map draws a blue sphere background and green countries, using TopoJSON shape data and TSV country names from the `world-atlas` package.
