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.

This example displays a choropleth map of geographic features rendered as SVG paths. It uses D3.js v5 to load the GeoJSON data, apply a Mercator projection with `d3.geoMercator`, and generate the path data via `d3.geoPath`. The TopoJSON library converts the datasource into GeoJSON features using `feature()`, while `d3.json` fetches the remote file before appending each path to the SVG canvas.

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 example generates an orthographic map of world features from a JSON dataset, rendering each geographic feature as a green SVG path with black stroke outlines. The code uses D3.js version 5’s `geoPath` and `geoOrthographic` projections, along with the topojson library’s `feature` function to convert the remote GeoJSON data into drawable paths. The map is displayed in a 900-by-500 pixel SVG element, with the projection offering a globe-like perspective.

This example shows how to create a world map using D3.js, rendering geographic features as SVG paths. It loads TopoJSON data from a remote URL and converts it to GeoJSON using the `feature` function from Topojson. The map uses a `geoNaturalEarth1` projection with a `geoPath` generator to draw each country boundary. The code imports specific D3 modules such as `select`, `json`, and `geoPath`, and appends path elements to an SVG canvas with a width of 960 and height of 500.

Let's make a map with D3.js!

This example shows a world map rendered as green SVG paths with black borders on a blue background. It uses D3.js v5 to load GeoJSON data from a GitHub repository and project it with a Natural Earth projection. The map is drawn by applying `d3.geoPath` with `geoNaturalEarth1` to each feature, while TopoJSON's `feature` function prepares the data. Styling is handled via CSS, and the visualization updates automatically once the remote data loads.

Let's make a map with D3.js!

This example visualizes a world map using D3.js with a blue sphere background and green country shapes. It loads geographic data from an external JSON file and renders it as SVG paths using the `d3.geoPath` and `d3.geoNaturalEarth1` projection. The code employs TopoJSON’s `feature` method (though not yet called in the visible portion) and logs the fetched data to the console. The styles define the sphere’s fill color and country borders with a low stroke opacity.
