This example shows a zoomable world map highlighting national borders and country names based on a CSV dataset. The map uses a natural Earth projection and renders geographic features with `d3.geoPath` and TopoJSON from the world-atlas package. Pan and zoom interactions are implemented with the `d3.zoom` API, while hover effects change country fills via CSS. The code fetches country names from a CSV file and builds a lookup table with `csv().then()` to attach tooltips.

Cheap tricks for interaction

This example shows a world map where hovering over a country turns it red, with country names available as tooltips. The map uses a Natural Earth projection and renders with SVG paths. The code loads world-atlas TopoJSON and TSV data, then uses `d3.geoPath` and `d3.geoNaturalEarth1` to draw countries. It also demonstrates a rudimentary zoom interaction via `d3.zoom`, though the zoom handler only logs to the console. The visualization relies on d3 v5 and d3-geo-projection for the projection.

Cheap tricks for interaction

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 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.

Cheap Tricks for Interaction

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 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 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.

Cheap Tricks For interaction

This example shows a world map with hover and zoom interactions. It renders country boundaries and names using a Natural Earth projection, with each country highlighted in red on mouseover. The visualization loads geographic data from the world-atlas TopoJSON dataset and joins it with country names from a TSV file. It uses d3.geoPath with d3.geoNaturalEarth1 to draw the map, d3.zoom to enable pan and zoom, and SVG title elements for tooltips.
