Forked from Circles

This example demonstrates mapping U.S. states from TopoJSON data, coloring California red and other states blue. It uses `d3.json` to fetch the data, `topojson.feature` to convert it to GeoJSON, and `d3.geoPath` to render the shapes as SVG paths. The code also includes ES6 module imports from local files and from D3, and appends SVG title elements with click handlers.

Loads D3 via UNPKG.
Demonstrates use of import from "d3".
Demonstrates use of import from local ES6 modules.

Fork of Fork of Fork of D3 world map example with TopoJSON to GeoJSON and circular indicators

This example displays a U.S. map with circular indicators, initially showing population-based circles over state boundaries. It converts TopoJSON to GeoJSON using `feature` and `mesh` from `topojson`, while `d3.geoPath` renders the SVG shapes. React hooks manage asynchronous data loading from a CDN via `d3.json`. The visualization uses `d3.scaleLinear` and `d3.scaleSqrt` to size and color the circles, though the render function currently outputs an empty SVG.

U.S. States TopoJSON

This example shows a map of the United States rendered as SVG paths, where individual states turn red when hovered. The map uses the TopoJSON `us-atlas` file, loaded via `d3.json`, and the code relies on the `topojson` library to convert the TopoJSON topology into geographic features. The rendering is done with `d3.geoPath` to project the geometry, and state borders are drawn as a separate path using a mesh that highlights each boundary. No interaction beyond the hover effect is implemented.

Fork of US states map

This example displays a choropleth map of US states, with each state filled by a categorical color assigned through `d3.scaleOrdinal` and `schemeCategory10`. It renders the map using `d3.geoPath` with a `geoAlbersUsa` projection, drawing state boundaries from TopoJSON county data loaded via `d3.json`. Hovering over a state turns it green through CSS, and each state includes an SVG `<title>` element showing its name.

Fork of Fork of Map

This example shows a choropleth map of U.S. states, with each state filled by a categorical color from `schemeCategory10`. The code loads county-level TopoJSON data from the `us-atlas` CDN and renders the boundaries using `d3.geoPath` with an `geoAlbersUsa` projection. State features are extracted via `topojson.feature`, and each path’s fill is assigned by a `scaleOrdinal` based on the state name, with a tooltip title appended. The visualization demonstrates a straightforward integration of D3’s geospatial and scale APIs.

Fork of USA map

This fork of the USA map displays state boundaries as SVG paths colored with a categorical scale. When hovering over a state, its fill color changes to red. Built with D3 v5, it uses `d3.geoAlbersUsa` for projection and `d3.geoPath` for rendering. State geometries come from the TopoJSON `us-atlas` dataset, processed via `topojson.feature`, with styling defined in CSS.

Fork of Fork of US states map : with colorScale. One color for each country

This example displays a choropleth-style map of African states, rendered as green SVG paths with white strokes on a dark background. It loads GeoJSON data from a GitHub gist, converts it into geographic features using `topojson.feature`, and projects the shapes with `d3.geoAlbersUsa` and `d3.geoPath`. Each state path includes a `<title>` element showing the region’s name from the data’s properties. The implementation relies on D3 v5 for selection, data loading, and path generation, while the map’s styling is defined in an external stylesheet.

Fork of Fork of ICE 8 - Country Map

This example displays a static map of the United States using state boundaries rendered as green SVG paths on a light blue background. The code employs D3 v4 with `d3.geoPath` and `d3.geoAlbersUsa` for projection, and reads TopoJSON data from the us-atlas package via `topojson.feature`. State shapes are drawn with stroke styling, and the map is centered using a manual translation offset within an SVG container.

Fork of Circles with D3

This example demonstrates a D3.js data join that renders a set of circles onto an SVG canvas, each positioned and styled according to attributes in a hardcoded data array. The code uses `select`, `attr`, and `join` to bind data to circle elements and set their `cx`, `cy`, `r`, and `fill` properties. It also loads TopoJSON country boundary data via `d3.json` and `topojson.feature` for an India map layer, though that map is not yet drawn. The visualization shows a simple, colorful scatter of overlapping circles on a light background.
