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 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 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 displays world countries colored in light green against a blue globe, with red highlighting on hover. The visualization uses a natural Earth projection via `d3.geoNaturalEarth1` and renders geographic features with `d3.geoPath`. Country boundaries and identifiers come from the World Atlas TopoJSON dataset, while country names are joined from a TSV file. Interactive tooltips show each country’s name through appended SVG `<title>` elements, and the map supports zooming via D3’s zoom behavior.

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 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 choropleth map visualizes world countries using a natural Earth projection, with color encoding driven by data loaded from the world-atlas TopoJSON and TSV files. The SVG rendering uses `d3.geoNaturalEarth1` and `d3.geoPath` to draw geographic features, while an ordinal color scale maps country attributes to fill colors. Interactive pan and zoom are enabled through `d3.zoom`, which transforms both the map and sphere layers. A color legend is positioned on the left side to interpret the scale.

Choropleth Map

This choropleth map displays the world’s countries, each filled with a light green color that turns red on hover, while the ocean remains blue. It uses D3 v5 and TopoJSON to load world-atlas data, combining a TSV file for country names with a JSON topology for geographic boundaries. The map is rendered with an SVG using a natural Earth projection via `d3.geoPath`, and interactive panning and zooming are enabled through `d3.zoom`.

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`.
