This choropleth map displays world countries as red-filled paths on a blue sphere using a natural Earth projection, with hover effects changing the fill to red. The visualization employs D3 v5’s `geoPath` and `geoNaturalEarth1` for geographic rendering, and TopoJSON’s `feature` to convert world-atlas 50m topology into GeoJSON. Data from a TSV file is merged with country IDs to attach country names for tooltips. The map supports zooming via D3’s `zoom` behavior, applying transforms to the SVG group.

Choropleth Map

This example presents a choropleth map of world countries rendered as an SVG using D3 v5. It displays each country as a red-filled path on a blue sphere, with country names shown in tooltips on hover. The visualization uses `d3.geoNaturalEarth1` for the projection, `d3.geoPath` for drawing, and `d3.zoom` for panning and zooming. Data loads from TopoJSON and TSV files via the world-atlas package, with `topojson.feature` processing geographic boundaries. Hover effects change fill color to red, while the base country color is also red, with black stroke outlines.

Choropleth Map

This choropleth map displays world countries using a natural Earth projection, with country boundaries rendered as interactive SVG paths. The visualization uses D3 v6 and TopoJSON to load and convert world-atlas data from unpkg, employing `d3.geoNaturalEarth1` and `d3.geoPath` for projection and path generation. Hovering over a country changes its fill from green to red, while a zoom behavior (`d3.zoom`) allows panning and scaling the entire map. The sphere background is filled blue, and country names appear as tooltips via SVG title elements.

Choropleth Map

This choropleth map visualizes world countries with a green fill and a blue sphere background, using a natural Earth projection rendered to SVG. It draws country boundaries and names from the world-atlas TopoJSON dataset, with each country’s name displayed as a tooltip. The map supports pan and zoom via d3.zoom, and hovering over a country turns it red. The code leverages d3.geoNaturalEarth1, d3.geoPath, and topojson.feature to generate the geographic paths.

Choropleth Map

This choropleth map visualizes world countries using a natural Earth projection, with each country filled in light green and outlined in black. The visualization loads geographic data from the World Atlas TopoJSON and TSV files, using `d3.geoPath` and `geoNaturalEarth1` to project and render country boundaries. Countries are colored by their assigned fill, and hovering over a country turns it red, while a tooltip displays the country name. The map includes a blue sphere background and supports zoom interactions through D3’s zoom behavior.

Choropleth Map

This choropleth map displays world countries on a natural Earth projection, colored uniformly with a light green fill on a blue sphere. It uses the `geoNaturalEarth1` projection and `geoPath` from d3 to generate the geographic paths from TopoJSON world data. The visualization supports zooming and panning via the custom `zoom` event, while hovering over a country turns it red. Data is loaded from the world-atlas package, which provides both TSV metadata and TopoJSON geometry.

Choropleth Map

This choropleth map displays world countries in solid red against a blue sphere, with each country labeled by name on hover. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to render geographic features from TopoJSON data loaded via the world-atlas package. Interactive zooming is implemented with D3’s zoom behavior, while country styling and hover effects are defined in CSS. The map draws all features as SVG paths, with a title element added per country for tooltip-like labels.

Choropleth Map

This choropleth map visualizes world countries using color to distinguish region boundaries and a blue sphere to represent the Earth’s surface. It loads geographic data from the World Atlas TopoJSON and TSV files via Promise.all, then renders each country as an SVG path using d3.geoPath with the d3.geoNaturalEarth1 projection. Hovering turns countries red, and tooltips display country names through appended title elements. The visualization supports zoom interaction via d3.zoom, with light green fills and black strokes for borders.

Choropleth Map

This choropleth map displays world countries as a stylized green landmass on a blue sphere, using a natural Earth projection. It renders with D3’s `geoPath` and `geoNaturalEarth1` projection onto an SVG, powered by TopoJSON world-atlas data. Hovering highlights a country in red, while a tooltip shows the country name from a TSV lookup. Pan and zoom are enabled via `d3.zoom`.
