This example displays an interactive map of India with state and district boundaries rendered as SVG polygons using React hooks and D3 v6. The code loads two TopoJSON files from GitHub Gists via `d3.json` and converts them with `topojson.feature`. A `geoMercator` projection and `geoPath` generator draw the map shapes, while React’s `useEffect` and `useRef` manage the D3 selections. The visualization updates when the bundled data arrives, filling polygons with a teal color.

Making map in react d3 method 1

This example demonstrates how to render a choropleth map of Indian states and districts using React and D3 v6. The application loads TopoJSON data from two external GitHub gists, converts it to GeoJSON features, and displays the map as an SVG path using D3’s geoMercator projection and geoPath generator. The map fills each state polygon with a teal color and updates when new geometry is fetched. The code uses React hooks (useRef, useEffect, useState) to manage the SVG selection and state data, with d3.json loading the TopoJSON and topojson.feature converting the topology.

Map with React & D3

This example renders a choropleth map of India using React and D3. It displays state boundaries as SVG paths, filled with a teal color, against the full browser viewport. The map is projected using `d3.geoMercator` and drawn with `d3.geoPath`, while TopoJSON data is fetched from a remote gist and converted to GeoJSON via the `feature` function. React components manage the data loading lifecycle and render the SVG elements, with D3 handling the geographic calculations.

Fork of Fork of india map

This visualization displays India’s states and districts as vector paths overlaid on a Mercator projection. The map distinguishes administrative levels with red state boundaries and brown district borders, while district fills use an ordinal color scale. It loads two TopoJSON datasets (state and district boundaries) and renders them as SVG paths using `d3.geoPath` and `d3.geoMercator`. The implementation also applies `d3.zoom` for interactive pan and zoom, with hover effects that highlight districts. The map is built with React and uses the `topojson` library to process the geographic features.

Fork of Fork of india map

This visualization displays a map of India with its states and districts, colored by state using a categorical color scale. It shows district-level boundaries with hover effects that turn districts black, and state boundaries with orange strokes. The map supports zooming and panning via d3.zoom. Built with React, it uses d3.json to load TopoJSON data from GitHub sources, d3.geoMercator for projection, and d3.geoPath to render the SVG paths.

Fork of India Map

This fork of an India map visualizes state-level boundaries with each state colored using a categorical color scale, and labels placed at state centroids. The code loads TopoJSON data from a remote source, converts it to GeoJSON using `topojson.feature`, and renders SVG paths via `d3.geoPath` with a `geoMercator` projection. State names are added as SVG text elements positioned with `pathGenerator.centroid`, and hover effects are styled in CSS.

Fork of Fork of Fork of india map

This visualization displays a zoomable map of India with all its districts and states, rendered as SVG paths. The map uses categorical colors for districts and overlays state boundaries with red strokes. Built with D3 v5, it employs `d3.geoMercator` for projection and `d3.geoPath` to generate paths from TopoJSON data. The map supports interactive zooming via `d3.zoom`, and hovering over districts changes their fill to silver, while tooltips show district and state names from the loaded data.

Fork of IndiaMap

This visualization displays a color-coded map of India’s states, with each state labeled by name and rendered using D3’s `geoMercator` projection and `geoPath` generator. State boundaries are drawn with a white stroke, and hovering over a state fills it white. The code loads TopoJSON data from a GitHub gist, applies a `scaleOrdinal` with `schemeCategory10` for fill colors, and positions state name labels at path centroids. It uses D3 v5, TopoJSON, and renders to SVG within a React project.

Fork of country map

This example displays a choropleth map of India, with each state colored according to a categorical color scheme. The visualization uses the Mercator projection via `d3.geoMercator` and renders geographic boundaries with `d3.geoPath`. GeoJSON data is fetched from a GitHub Gist, parsed with `topojson`'s `feature` function, and drawn as SVG paths. The map is built with D3 v5, React, and a CSS hover effect that changes state fill colors.
