Cheap Tricks for Interaction

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 rendered with SVG, where country boundaries appear in light green and turn red on hover, with a blue sphere background. It uses `d3.geoNaturalEarth1` for projection and `d3.geoPath` to draw geographic features from TopoJSON data loaded via `d3.json`. Country names come from a TSV file accessed with `d3.tsv`. The map supports pan and zoom through `d3.zoom`, applying the current transform to a group element containing all countries.

This example shows an interactive world map with zoom and pan capabilities, where country boundaries are drawn in light green and highlight in red on hover with name tooltips. It uses d3.geoNaturalEarth1 projection, d3.geoPath for rendering, and d3.zoom for the pan/zoom interaction. Country data comes from the world-atlas TopoJSON dataset, paired with TSV names, and the tooltips are implemented with SVG title elements. Styling uses simple CSS for hover effects and sphere coloring.

This example shows a zoomable world map with hover highlighting, using a natural Earth projection to render country boundaries from TopoJSON data. The map supports interactive pan and zoom through d3.zoom, with a tooltip title displaying each country’s name from a TSV lookup. Countries fill light green and turn red on hover via SVG styling. The visualization relies on d3.geoPath, d3.geoNaturalEarth1, and topojson.feature to draw geographic shapes.

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.

This example shows an interactive world map where hovering over a country turns it red and zooming with the mouse repositions the map. It uses D3.js v5 with `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for rendering, and `d3.zoom` to handle pan and zoom transforms on the SVG group. Country boundaries come from the `world-atlas` TopoJSON file, with names joined from a TSV file. The visualization demonstrates fundamental DOM selection and data binding, alongside simple CSS hover styling.

This example presents an interactive world map using D3.js and TopoJSON. It displays country boundaries from the world-atlas 50m dataset, rendered as SVG paths using the `geoNaturalEarth1` projection and `geoPath`. The map supports zooming via the `zoom` function, which applies a transform to the grouped elements. Hovering over a country highlights it in red through CSS, and clicking the sphere logs an event to the console, while country names appear as tooltips from a TSV lookup file.

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.
