Forked from Fork of D3 Starter

This example displays a world map colored by per-country values from a small CSV dataset, using a blue sequential color scale to encode the data. It loads GeoJSON country boundaries from the world-atlas TopoJSON dataset and renders them as SVG paths with a Mercator projection (d3.geoMercator). The visualization relies on d3.json for fetching, topojson.feature for conversion, and d3.geoPath to generate the map shapes.

Fork of D3 Starter-map

This visualization shows a world map rendered with randomly colored countries using a natural Earth projection. The map fills the browser viewport and uses D3.js for the SVG rendering, with TopoJSON converting the world-atlas dataset into GeoJSON features. The code applies `d3.geoNaturalEarth1()` for projection and `d3.geoPath()` to generate the country paths, while `d3.interpolateBlues` assigns each country a random blues-scale color. The data loads from the world-atlas TopoJSON file via `d3.json()`.

Fork of D3 Starter-likitha

This example displays a world map with countries rendered in randomly selected shades of blue. The visualization uses a Natural Earth projection via `d3.geoNaturalEarth1` and generates paths with `d3.geoPath`. Country boundaries come from a TopoJSON file loaded from the world-atlas package, converted to GeoJSON with the `topojson.feature` function. Each country path is appended to an SVG and colored using `d3.interpolateBlues` with a random value, while the map fills the full viewport.

This interactive map displays country boundaries with colors representing continents, using an orthographic projection that rotates as the user drags the globe. The visualization loads world-atlas data from TSV and TopoJSON files, then fixes specific country discrepancies before rendering. It uses `d3.geoPath`, `d3.geoOrthographic`, `d3.zoom`, and `d3.drag` for interaction, with continent colors assigned via `d3.scaleOrdinal` from the Tableau10 scheme. Hovering highlights a country in red, while the title element shows the country name and index.

Fork of HTML Starter

This example displays a world map colored by values joined from a CSV dataset, with a hover tooltip showing each country’s name and numeric value. It renders an SVG using D3 v7’s `d3.geoNaturalEarth1` projection and `d3.geoPath`, loading country boundaries from TopoJSON via `world-atlas`. Country colors are assigned through a sequential `d3.scaleSequential` interpolator, while the CSV is joined using a `Map`. The tooltip appears on mouseover events, positioned at the cursor.

Fork of World Map with D3.js!

This example displays a world map as an SVG graphic, with each country rendered as a green path with black outlines. Hovering over a country changes its fill color to orange, providing basic user feedback. The visualization uses D3 v5 functions such as `select`, `json`, `geoPath`, and `geoEquirectangular` for the projection, while TopoJSON’s `feature` method converts the loaded world-atlas countries-110m.json data into GeoJSON features for rendering.

Fork of Let's make a map with D3.js!

This map visualization displays world countries as filled green regions on a blue sphere, rendered entirely with SVG. It loads geographic data from the World Atlas TopoJSON file using `topojson.feature` to extract country boundaries, then projects them with a Mercator projection via `d3.geoMercator` and `d3.geoPath`. The code appends a sphere outline path and draws each country as a separate `path` element, with styling applied through CSS classes for fill and stroke.
