d3 Visualization Map

This example displays a zoomable world map using a natural Earth projection, with countries colored light green and the ocean rendered as a blue sphere. Built with D3 v5 and TopoJSON, it loads country boundaries from the world-atlas dataset (50m.json) and names from 50m.tsv. The map supports interactive pan and zoom via d3.zoom, while d3.geoPath and geoNaturalEarth1 handle geographic rendering. Countries highlight red on hover, with tooltips showing country names. The visualization is rendered as SVG, with the sphere and country paths generated from the projected GeoJSON features.

Maps

This example renders a world map using D3.js and TopoJSON, displaying countries as light green shapes against a dark blue spherical background. It uses d3.geoNaturalEarth1 for the projection and d3.geoPath to generate SVG paths from the world-atlas dataset. The code loads TopoJSON data, converts it to GeoJSON with topojson.feature, and appends country paths to an SVG container. The visualization demonstrates basic data binding and DOM manipulation while showing geographic features with minimal styling.

Map

This example visualizes world countries as a choropleth-style map, coloring each country green with white borders on a dark blue spherical backdrop. The map renders as SVG using D3.js with a Natural Earth projection via `d3.geoNaturalEarth1`, and country boundaries are generated through `d3.geoPath`. Geographic data loads from the world-atlas TopoJSON file (countries-110m.json), which is converted to GeoJSON using the `feature` function from the topojson library. Hovering a country changes its fill to red, and each country includes a title tooltip displaying its name.

MAP

A map of world countries renders as SVG paths, with each country colored white and outlined in dark grey, while oceans appear light blue. Hovering a country turns it light blue. The visualization uses D3 v5’s `geoNaturalEarth1` projection and `geoPath` to draw the sphere and country boundaries from the world-atlas TopoJSON dataset, with `topojson.feature` converting the raw data into features. Zooming is enabled via D3’s `zoom` behavior, which applies transforms to the map group.

Maps Started

This interactive map of the world renders countries as green SVG paths with hover highlighting in red. It loads GeoJSON from the world-atlas TopoJSON dataset and country names from a TSV file, then joins them by ISO numeric code to display each country’s economy type as a tooltip on hover. The map uses the `geoNaturalEarth2` projection and `geoPath` from d3-geo-projection, and supports pan and zoom through d3’s `zoom` behavior applied to the SVG group.

Map with D3.js

This map visualization displays world countries on a natural Earth projection using D3.js and TopoJSON data from the world-atlas dataset. It renders an SVG sphere background and country paths filled with teal, which turn red on hover through CSS. The code employs D3 v6 features like `geoNaturalEarth1` and `geoPath` to project geographic coordinates, while `topojson.feature` extracts country boundaries from the loaded TopoJSON file. A tooltip showing each country’s name appears via appended `title` elements.

World test

This visualization displays a world map with countries colored light green against a blue sphere, using natural Earth projection. Hovering over a country turns it red, and users can zoom and pan the map interactively. The code loads TopoJSON and TSV data from the world-atlas package, converting TopoJSON to GeoJSON via topojson.feature and rendering paths with d3.geoPath. Zoom behavior comes from d3.zoom, while country names are joined from the TSV file and shown as SVG title tooltips.

World map

This interactive world map displays country boundaries using a natural Earth projection, with hover tooltips showing country names and zoom/pan controls for exploration. It loads geographic data from the world-atlas TopoJSON and TSV files, then renders countries with D3’s `geoPath` and `geoNaturalEarth1`. The visualization uses `d3.zoom` for interaction and `topojson.feature` to convert TopoJSON geometry, with hover effects styled via CSS.
