This map of d3 displays the world’s countries as green, stroked polygons, using a Mercator projection. The data comes from the world-atlas GeoJSON file, which is loaded via d3.json and converted into geographic features with topojson’s feature function. The code uses d3.geoPath and d3.geoMercator to generate the SVG paths, while d3.select appends each country’s shape to the canvas. Population figures from the included data.csv are not visualized in this example.

d3 World Map

This visualization displays a world map using an orthographic projection, with countries rendered as light green polygons that highlight orange on hover. The code loads geographic data from the world-atlas package via TopoJSON and joins it with country names from a TSV file. Using d3.geoPath and d3.geoOrthographic, it draws the globe’s sphere and country boundaries as SVG paths, with tooltips showing each nation’s name via appended title elements. The implementation relies on d3.v5, topojson-client, and a React-friendly structure with Promise.all for asynchronous data loading.

Map with D3.js

This map displays the countries of the world in light green with black outlines, colored red on hover. The map supports zooming and panning through D3’s zoom module and geoMercator projection. It renders country shapes as SVG paths generated with d3.geoPath, using world-atlas data from TopoJSON and TSV files for country names. The code employs d3.select, d3.json, d3.tsv, and the topojson feature function to construct the visualization.

Map D3

This map shows the countries of the world on a natural Earth projection, with oceans in blue and landmasses in light green. The visualization uses `d3.geoNaturalEarth1` as the projection and `d3.geoPath` to generate the SVG paths for each country. It loads world boundary data from the world-atlas package in TopoJSON format, then converts it to GeoJSON using the `topojson` library’s `feature` function before rendering. The entire graphic is drawn as SVG elements.

Let's make a map with D3.js!

This example displays a world map of countries rendered as light green SVG paths on a dark blue background. It uses the world-atlas TopoJSON dataset and D3’s `geoMercator` projection with `geoPath` to generate the shapes. The topojson `feature` method extracts country geometries, which are appended as SVG `<path>` elements. The map is static, with thin black strokes and low stroke opacity defining country borders.

Let's make a map with D3.js!

This example demonstrates how to create a map of the world using D3.js, rendering countries as green polygons with a blue sphere background. The visualization loads geographic data from the world-atlas TopoJSON file and converts it into GeoJSON features using the topojson library. D3’s geoNaturalEarth1 projection and geoPath generator handle the coordinate mapping and SVG path creation, while the code appends each country as a separate path element to the SVG canvas.

Let's make a map with D3.js!

This example renders a world map of countries using D3.js and TopoJSON. It loads geographic data from the world-atlas dataset and displays country boundaries as SVG paths. The visualization uses `d3.geoMercator` for the projection and `d3.geoPath` to generate the path data from the TopoJSON features. Each country is appended as a `path` element to an SVG canvas sized 960 by 500 pixels.

D3.js Map

This map visualization displays world countries on a natural Earth projection, allowing users to click individual countries to toggle their fill between light green and red. Built with D3.js v5 and TopoJSON, it loads geographic data from the world-atlas package and country names from a TSV file. The visualization uses d3.geoPath and d3.geoNaturalEarth1 for rendering, with d3.zoom enabling pan and zoom interactions on the SVG canvas.

D3 World Map

This visualization shows a world map rendered as SVG paths using a D3 Mercator projection. The map displays country boundaries loaded from a TopoJSON file, selected via `topojson.object` and drawn with `d3.geo.path`. A separate bar chart built with `scaleLinear` and `scaleBand` visualizes population data from a CSV file, showing values for labeled countries. The example demonstrates combining geographic and categorical data in a single D3 visualization.
