This example shows a zoomable world map colored by country, with each country’s name appearing as a tooltip on hover. The visualization uses d3.zoom to enable pan and zoom transformations on the SVG group, while d3.geoPath with a geoNaturalEarth1 projection renders the geographic outlines. Country boundaries come from the world-atlas TopoJSON dataset, with names matched via TSV data. Hovering highlights a country in red via CSS, and d3.append adds title elements for the tooltips.

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 a zoomable world map with country name tooltips, rendered as an SVG using D3 v5 and TopoJSON data from the world-atlas package. It displays natural Earth projection with interactive pan and zoom via d3.zoom, while country boundaries are drawn with d3.geoPath. Hovering highlights countries in orange through CSS, and each path appends a <title> element populated from the TSV dataset for native browser tooltips. The map uses a simple geoNaturalEarth1 projection with a steelblue sphere background.

Cheap Tricks for Interaction

This example shows a world map highlighting countries in light green on a blue sphere, with a red hover effect on individual countries and zoom-and-pan interaction. It uses D3 v5 with d3.geoNaturalEarth1 projection, d3.geoPath, and d3.zoom to enable the viewport transformations. Country boundaries come from the World Atlas TopoJSON dataset, while country names are matched via the accompanying TSV file. The map renders as SVG, with hover tooltips provided by native `<title>` elements.

Cheap Tricks for interaction

This example demonstrates a zoomable, hover-highlighted world map using D3 v5. It renders country boundaries and a blue sphere backdrop via `d3.geoPath` with a Natural Earth projection, pulling geometry from the world-atlas TopoJSON dataset. The visualization supports interactive pan and zoom through `d3.zoom`, applying transforms to an SVG group, and changes country fill to red on hover via CSS. Country names are joined from a TSV file using ISO numeric IDs.

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.

Cheap Tricks for Interaction

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.

Cheap Tricks for Interaction

This example demonstrates a zoomable world map with country outlines and hover highlighting, rendered as SVG. The map uses D3's `geoNaturalEarth1` projection and `geoPath` to draw country shapes from the world-atlas TopoJSON dataset, with a sphere background. Interactive zoom is implemented via D3's `zoom` module, which applies a transform to the map group on zoom events. Country names are joined from TSV data, and hovering over a country fills it red via CSS `.country:hover`. The visualization is built with React and D3 v5.

Cheap Tricks for Interaction

This example displays a world map rendered as an SVG using a natural Earth projection, with countries colored light green on a blue sphere. Hovering over any country turns it red, and the entire map can be panned and zoomed. The visualization loads TopoJSON world data and a TSV file of country names from the world-atlas package, then creates map paths with `d3.geoPath`. Zoom interaction is handled through `d3.zoom` and event transforms, while hover styling is applied via CSS on the `.country` class, with tooltips provided by SVG `<title>` elements.
