D3 test

This example visualizes a historical route from a GeoJSON file, displaying daily segments as dashed black polylines over a light blue graticule-filled map. The code uses D3 v5 with an SVG rendering approach and a Mercator projection configured via `d3.geoMercator()`. It loads coastline and route data with `d3.json()`, then binds the features to SVG paths using `d3.geoPath()`. The graticule is generated with `d3.geoGraticule()`. The visualization clearly shows the path’s progression across the mapped region, with each day’s travel distinguished by styling properties like stroke dasharray.

Let's make a map with D3.js!

This example demonstrates how to build a map visualization using D3.js, displaying geographic features as green polygons with black outlines on a blue background. It loads GeoJSON data from a remote URL and renders it as SVG paths using the `geoPath` generator with the `geoAiryRaw` projection from d3-geo-projection. The code relies on `d3.json` for data loading and topojson’s `feature` conversion, with all styling defined in external CSS.

Let's make a map with D3.js!

This example visualizes a world map using a natural Earth projection, with countries rendered as green SVG paths against a blue sphere background. It loads geographic data from the World Atlas TopoJSON file and converts it to GeoJSON with `topojson.feature`. The visualization uses D3 v5’s `d3.geoPath` and `d3.geoNaturalEarth1` to project and draw the map, while CSS styles the sphere and country boundaries.

Let's make a map with D3.js!

This example shows a simple world map rendered with D3.js, displaying geographic features as green filled paths with black borders against a blue background. The visualization loads GeoJSON data from a remote GitHub URL using `json()` and applies `geoPath()` from the d3-geo module to generate the SVG path data. With topojson-client’s `feature()` method, the code binds the geographic features to `path` elements in an SVG canvas via `selectAll()`. The map is static, with styling defined in CSS, and serves as a basic introduction to mapping with D3 v5.

Let's make a map with D3.js!

This example displays an orthographic map of the world, rendered as green SVG paths with black outlines on a blue background. It loads geographic data from a remote JSON file and projects it using `d3.geoOrthographic` and `d3.geoPath`, while `topojson.feature` converts the TopoJSON input into GeoJSON features. The map is static, with no interaction or animation, and serves as a simple demonstration of generating a globe-like projection with D3.js v5.

Let's make a map with D3.js!

This visualization presents a map of geographic regions, with each area rendered as a solid green path outlined in black. The map is drawn using SVG paths generated from GeoJSON data, which is loaded from an external URL. The code employs D3.js version 5 functions such as `d3.json` to fetch the data and `d3.geoPath` to construct the path geometries, while the TopoJSON library's `feature` function is used to process the geographic features. The resulting paths are appended to the SVG canvas with a fixed width and height, and CSS styles define the fill and stroke colors.

Let's Make a Map With D3.js !

This example displays an interactive world map rendered with SVG paths, using D3.js v5 and TopoJSON data from the world-atlas package. It shows country boundaries with hover effects, built using `geoNaturalEarth1` projection and `geoPath` for geometry generation. The map supports pan and zoom through D3’s `zoom` behavior, transforming a group element. Country names are loaded from a TSV file and appended as SVG `<title>` tooltips, while the styling is defined in an external CSS file.

Let's make a map!

This example renders an interactive orthographic globe using D3’s `geoOrthographic` and `geoPath` projections. It loads world country boundaries from TopoJSON and country names from a TSV file, then displays each country as a light-green SVG path that turns red on hover, with tooltips showing the country name. The globe itself is drawn as a dark-blue sphere, and all interactions rely on D3’s data join and selection methods.
