This example displays a choropleth-style map of India rendered as SVG paths, with each state filled using a categorical color scale from `schemeCategory10`. The visualization uses `d3-geoMercator` for projection and `d3.geoPath` to generate the state boundaries from TopoJSON data loaded via `d3.json`. A zoom interaction is enabled, and hovering over a state changes its fill to grey via CSS. The map includes a title and is built with React, though the core logic relies on D3 v5 and the `topojson` feature API.

country map

This example displays a choropleth map of India, rendering each state as a distinct colored path using geographic features loaded from a GitHub gist. The visualization employs a Mercator projection via `d3.geoMercator` and converts TopoJSON data to GeoJSON features with the `topojson.feature` function. Each state is drawn as an SVG path generated by `d3.geoPath`, with fill colors assigned from `d3.scaleOrdinal` and `schemeCategory10`. The map includes a title and uses hover styling, with all rendering handled through React and D3 v5.

Country Map

This example displays a choropleth map of India rendered as an SVG, with each state filled using a categorical color scale. The visualization uses D3’s `geoMercator` projection, `geoPath`, and `scaleOrdinal` to draw the country’s boundaries from a TopoJSON file hosted on GitHub. Title text appears above the map, and hovering over any state highlights it in red via CSS. The code relies on the D3 v5, TopoJSON, and d3-geo-projection libraries.

Country map fork

This example displays a choropleth map of India using the Mercator projection, with each state colored via a categorical color scale. The visualization renders SVG paths derived from TopoJSON data fetched from a GitHub gist, using `d3.geoPath` and `d3.geoMercator` for geometry and projection. The code employs `d3.select`, `d3.json`, `d3.scaleOrdinal`, and `schemeCategory10` for styling, while the `country` class applies a hover effect that turns regions yellow. The map is built within a React framework using D3 v5.

IndiaMap

This example renders a choropleth map of Indian states, with each state filled by a categorical color and labeled with its name. It uses D3 v5’s `geoMercator` projection and `geoPath` to convert TopoJSON geometries into SVG paths, while `scaleOrdinal` and `schemeCategory10` assign colors. State boundaries are emphasized with white strokes, and hovering turns a state white. Data comes from a remote TopoJSON file, and the map is displayed within a fixed-width SVG on a teal gradient background.

country map

This example displays a choropleth map of India, rendered as SVG paths using the Mercator projection. The map visualizes the country’s regions with categorical colors from `d3.scaleOrdinal` and `schemeCategory10`, and each region shows a tooltip title on hover. The code loads TopoJSON data from a GitHub gist via `d3.json`, parses it with `feature` from the topojson library, and draws paths using `d3.geoPath`. Hovering changes the fill color to pink, and the map includes a heading text layer.

India Map

This example displays a choropleth-style map of India, rendering each state as a green SVG path against an orange background. It uses React for component structure and d3’s `geoMercator` projection with `geoPath` to convert TopoJSON geographic data into scalable vector graphics. The map loads state boundaries from a remote gist URL via `d3.json`, processes them with `topojson.feature`, and fills the viewport dynamically. The visualization is simple and static, focusing on clear geographical layout rather than interactivity or data encoding.

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.

India Map

This example displays a choropleth map of India’s states, with each state filled by a distinct color from d3’s `scaleOrdinal` and `schemeCategory10`. Using topojson data loaded from a remote GitHub repository, the code projects the geometry with `d3.geoMercator` and renders it as SVG paths via `d3.geoPath`. State names are positioned at each polygon’s centroid, while hover effects and a light pink stroke are defined in the accompanying CSS. The visualization relies on the D3 v5 library and topojson for geographic feature extraction.
