This example displays a choropleth map of Australia, showing state boundaries and labels with hover-based population tooltips. It uses a Mercator projection centered on the country via `d3.geoMercator()` and renders geographic features as SVG paths through `d3.geoPath()`. State polygons are styled with a light fill that darkens on mouseover. The map loads GeoJSON data from a remote gist, and labels are positioned using `path.centroid()`. A custom tooltip div reveals the population property for each state on hover.

Australia Map

This example presents a choropleth-style map of Australia, with each electoral region filled with a distinct color from `d3.schemeCategory10` and labeled with its name. The code uses `d3.geoMercator` to project the geographical data and `d3.geoPath` to generate SVG paths for each region. State and territory names are positioned using the centroid calculation from `d3.geoPath`. The map is rendered as an SVG, with data loaded from a TopoJSON file and processed using the `topojson.feature` API.

Country Map

This example displays a map of Australia’s administrative regions, with each state filled in red and labeled with its name. The visualization loads GeoJSON data from `australia.json` and projects it using `d3.geoMercator` with a custom translation and scale. It uses `d3.geoPath` to generate SVG paths for the regions and `topojson.feature` to extract the geometry. State names are positioned at each region’s centroid using `d3.geoPath.centroid`, rendered as SVG text elements with a small font size.

Australia Map

This example displays a choropleth map of Australia, with each electoral region filled with a distinct categorical color and labeled with its name. Using D3 v5 and TopoJSON, it loads the `australia.json` topology, converts the `2021_ELB_region` object into GeoJSON features, and renders them as SVG paths via `d3.geoPath` with a Mercator projection. A `d3.scaleOrdinal` with `schemeCategory10` determines fill colors, while state names are positioned at path centroids. The map includes red stroke outlines for all region boundaries.

Map

This example displays a choropleth map of Indian states, with each state filled by a distinct categorical color and labeled with its name. It uses D3 v4's `d3.geoPath` with the `d3.geoMercator` projection to render SVG paths from TopoJSON data, and `d3.scaleOrdinal` with `schemeCategory10` for coloring. State labels are positioned using the path generator's centroid method. The map also generates tooltips via appended `title` elements, loading geographic data from a remote TopoJSON source.

map exemple

This choropleth map displays global population estimates, with countries shaded from light red to dark red according to their population size. The visualization uses `d3.geoMercator` for projection and `d3.geoPath` to render country boundaries from TopoJSON data loaded via `d3.json`, while population values come from a TSV file loaded with `d3.tsv` and mapped to colors using `d3.scaleLinear`. The map supports pan and zoom interactions through `d3.zoom`, and hover effects are styled with CSS.

Maps-Exemple

This example displays a choropleth map of world countries colored by population estimates, with hover highlighting and zoom/pan interaction. It uses D3 v5’s `d3.geoMercator` projection and `d3.geoPath` to render SVG paths from TopoJSON data loaded from the world-atlas package, while population values and country names come from a supplementary TSV file. A linear `d3.scaleLinear` maps population magnitudes to a red color ramp, and the `d3.zoom` behavior applies transforms to all country paths.

Fork of Australia Map

This example displays a choropleth map of Australia’s administrative regions, rendered as red-filled paths with white strokes on an SVG canvas. It uses d3.geoMercator with a clipped projection and d3.geoPath to draw the features, while topojson’s feature method converts the loaded state and district datasets into GeoJSON. The map supports zooming via d3.zoom, and d3.scaleOrdinal with schemeCategory10 assigns categorical colors, though the current styling overrides fills with a uniform red.

D3 - World Choropleth

This example displays a world choropleth map of population in 2023, using a Mercator projection and a yellow-to-red sequential color scale to represent each country’s population. The map is rendered as SVG paths, with a tooltip that appears on hover showing the country name and population. The code loads GeoJSON and CSV data via D3’s `d3.queue` and `d3.json`/`d3.csv` APIs, and it builds the choropleth using `d3.geoPath` with a projected path generator. A legend is added using the `d3.legend` library, and the project utilizes D3 v4, `d3-scale-chromatic` for the color interpolation, and `d3-geo-projection` for the map projection.
