This example shows an interactive world map with country boundaries, rendered using the Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`. Users can zoom and pan the map with the mouse, as the code applies `d3.zoom` to the SVG container and updates a group’s `transform` attribute on each zoom event. Country names appear as tooltips when hovering, populated from a TSV file that maps ISO numeric codes to names, while the underlying geometry comes from a TopoJSON file loaded via `topojson.feature`. The map uses filled paths with hover color changes defined in CSS.

Cheap Tricks for Interaction

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.

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.

This example demonstrates interactive pan and zoom on a natural Earth projection map. The visualization renders country boundaries from TopoJSON world-atlas data using `d3.geoNaturalEarth1` and `d3.geoPath`, with hover highlighting via CSS. The code applies `d3.zoom` to the SVG container, updating a transform attribute on a group element during zoom events. Country names from the `world/50m.tsv` file appear as tooltips using SVG `<title>` elements, while the sphere background and country fills come from external styles.

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 built with D3 v5 and TopoJSON, using a Natural Earth projection. Users can pan and zoom the map via the `d3.zoom` API, with the viewport transform applied to a group element. Country boundaries are rendered as SVG paths via `d3.geoPath`, with hover highlighting controlled by CSS. The map loads world-atlas data from unpkg, joining TopoJSON features to TSV country names for tooltips.

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`.

Cheap Tricks for Interaction

This example shows a zoomable world map rendered as an SVG, with country names displayed as hover tooltips. The visualization uses a Natural Earth projection via `d3.geoNaturalEarth1` and `d3.geoPath`, with geographic data loaded from the World Atlas TopoJSON and country names from its accompanying TSV file. The map supports pan and zoom through `d3.zoom`, and the code includes a commented-out `d3.behavior.zoom` variant. Country boundaries are drawn as light green paths with black strokes, while the ocean sphere is filled blue.

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.
