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.

This example shows an interactive world map rendered in SVG, with country boundaries displayed in light green and a blue sphere backdrop. Users can zoom and pan the map using their mouse or touch gestures, while hovering over a country highlights it in red and reveals its name as a tooltip. The visualization uses D3 v5’s `geoNaturalEarth1` projection, `geoPath`, and `zoom` behavior, with TopoJSON data from the world-atlas package. Country names are joined from a TSV file using ISO numeric codes, and the map is drawn from TopoJSON features converted with `feature`.

This example shows an interactive world map where hovering over a country highlights it and clicking selects it, turning it red. The visualization uses the D3.js library, specifically `d3.geoNaturalEarth1` for the map projection and `d3.geoPath` for rendering country boundaries. It loads geographic data from the `world-atlas` package via `d3.json` and `d3.tsv`, using `topojson` to convert the TopoJSON features. The map supports zooming through the `d3.zoom` API, which dynamically transforms the SVG group containing the paths.

This example shows an interactive world map rendered in SVG, where each country appears in light green with a black outline and displays its name via a tooltip on hover. Users can pan and zoom the map using mouse interactions, which transforms the entire map group. The visualization uses D3 v5 with `d3.geoNaturalEarth1` for projection, `d3.geoPath` for drawing country boundaries, and `d3.zoom` for interaction. Country geometries come from the world-atlas TopoJSON dataset, with country names loaded from a matching TSV file, while CSS hover effects turn countries red under the cursor.

This example shows an interactive world map, where hovering over a country highlights it in red and reveals its name in a tooltip. The map uses a natural Earth projection rendered as SVG paths, with a blue sphere background. Interaction is powered by D3's `zoom` module for pan and zoom, while country boundaries and names come from the `world-atlas` dataset loaded via D3's `tsv` and `json` helpers. The `topojson` library converts the raw topology data into geoJSON features for rendering.

Cheap Tricks for Interaction

This example shows a world map rendered with SVG paths using D3 v5 and TopoJSON world-atlas data. Clicking a country triggers a simple interaction, though the current handler only logs to the console; countries highlight red on hover. The map uses a natural Earth projection (`geoNaturalEarth1`) with zoom support via `d3.zoom`, and country names come from a TSV file joined by ISO numeric ID.

Cheap Tricks for Interaction

This example shows an interactive world map where hovering highlights countries in red against a light green base, with zoom and pan enabled for exploration. The visualization uses D3 v5 with a Natural Earth projection (d3.geoNaturalEarth1) and d3.geoPath to render country boundaries from TopoJSON world atlas data, linked to country names via TSV metadata. Interactions rely on d3.zoom for panning and zooming, while CSS :hover rules change country fill colors. The SVG-based map includes a blue sphere background, and the code loads data using Promise.all with d3.json and d3.tsv.

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.
