This example provides TopoJSON map files and associated name-to-code dictionaries for creating geographic visualizations. It includes data for Russian regions and world countries, with each topology containing geometry objects and properties. The files are structured for use with the TopoJSON format, enabling efficient encoding of geographic boundaries. Dictionary files map region names to ISO codes, facilitating data joins for choropleth maps or interactive applications with libraries like D3.

TopoJSON Collection

This example presents a gallery of TopoJSON files converted from original shapefiles and GeoJSON sources, covering world countries, continents, and administrative subdivisions by country. The visualization uses d3.v4 and renders a static SVG scene with a text caption, as the core function is to make the collection discoverable rather than display mapped data. The code initializes an SVG canvas and adds a label referencing the repository’s README, while the data sources are documented as Natural Earth and DIVA-GIS.

topojson example data

This example displays a map of Spanish municipalities using a TopoJSON file from a Gist by Jn1532. The visualization renders geographic boundaries as vector paths with `d3.geoPath`, while the code also defines multiple data fields for interactive features. The JSON structure contains topology arcs and coordinate arrays, which are processed and drawn through the D3.js library. The rendering approach focuses on the raw geographic data rather than an interactive interface, showing how TopoJSON encodes complex spatial relationships.

TopoJSON

This visualization displays a world map rendered as a sphere using the TopoJSON format. The map shows country boundaries in blue with no fill, projected using the geoEqualEarth projection. The code loads geographic data from a gist, converts TopoJSON to GeoJSON using topojson’s `feature` function, and renders paths with d3’s `geoPath`, all within a React component drawing to SVG.

Topojson Map

This example displays a world map rendered as filled country polygons on a sphere background. It uses d3.json to load TopoJSON data from the world-atlas package, then converts it to GeoJSON features with topojson.feature. The map is drawn in SVG using d3.geoPath with a d3.geoNaturalEarth1 projection, styling countries in green and the sphere in dark blue.

Topojson World Map

This example displays a world map in the Natural Earth projection, rendering countries as green polygons with a blue spherical background. It visualizes the topojson-format country boundaries from the world-atlas dataset. The code uses `d3.geoPath` with the `geoNaturalEarth1` projection to generate SVG paths, while the `topojson` library’s `feature` function converts the topojson data into GeoJSON features.

Topo.JSON grid that can be used as pixel art on a map or a charting solution

This grid-based TopoJSON file defines 100×100-pixel cells that can be assembled into a larger raster-like map. The geometry uses a repeating pattern of square arcs, each with an identical side length, which lets developers render the data as pixel art on a map or as a discrete grid in a charting library. The author, Hugoberry, published this as a Gist, likely as a lightweight, code-driven way to experiment with topojson without needing external shapefiles.

world map for Topojson data

This example displays a world map rendered from TopoJSON data, with countries shown as grey filled paths with cyan strokes against a light pink globe background. It uses d3.geoPath with a d3.geoNaturalEarth1 projection to generate SVG paths from geographic features. The code loads the TopoJSON file via d3.json and converts it to GeoJSON using topojson.feature. The visualization framework is D3 v5, with map styling controlled through the stylesheet’s `.country` and `.globe` classes.

World Map with Topojson data

This example displays a world map using TopoJSON data, rendering countries as blue-filled paths with pink strokes against a white spherical backdrop. It uses D3 v5’s `geoMercator` projection and `geoPath` to convert geographic coordinates into SVG paths, while the TopoJSON library’s `feature` method extracts country geometries from a remote JSON file. The visualization loads data asynchronously via `json` and appends each country path to the SVG canvas, demonstrating a straightforward choropleth-free baseline of global boundaries.
