This visualization displays a choropleth map of India, using a Mercator projection to render the country’s geographic boundaries as SVG paths. The map is colored using a categorical color scale (`d3.scaleOrdinal` with `schemeCategory10`), and individual regions change to a pink hover color via CSS. The geographic data is loaded as a TopoJSON file from a GitHub gist, parsed with the `topojson` library’s `feature` function, and drawn using `d3.geoPath`. The map is built with React, with an interactive header and styled via an external stylesheet.

country map

This interactive visualization displays a choropleth map of India rendered as SVG paths. Using D3 v5 with the geoMercator projection and geoPath API, it draws country boundaries with colors assigned via scaleOrdinal. Data is loaded from a Gist-hosted TopoJSON file and parsed through the topojson library’s feature function. Hovering highlights regions in violet. The visualization also includes a white header text, with styling handled by an external CSS file.

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.

India Map

The example displays a choropleth-style map of Indian states and territories, rendered as orange SVG paths on a full-screen canvas. It draws geographic boundaries using a Mercator projection centered on the country, with `d3.geoPath` converting GeoJSON features into SVG path data. The map data is loaded remotely from a TopoJSON file, which is converted to GeoJSON via `topojson.feature`. The visualization is built with React components, where the `Map` component receives the parsed feature collection and applies the projection, while React manages the overall SVG rendering.

Country Map of India

This example renders a choropleth map of India using D3.js and TopoJSON. The visualization applies the Mercator projection through thegeoMercator and geoPath APIs to draw state boundaries, with each region colored using a categorical color scheme. The map loads geographic data from a remote TopoJSON file and renders it as SVG paths, with a hover effect that highlights individual states in pink. The interface displays the map within an SVG canvas, with the state names and colors derived from the dataset's properties.

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.

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.

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.

India Map

This example displays a static map of India rendered as a set of coral-colored SVG paths. The map loads TopoJSON data from a GitHub gist, converts it to GeoJSON features using the `topojson` `feature` function, and projects each feature with D3’s `geoMercator` and `geoPath`. Built with React, the visualization fetches the data asynchronously via `d3.json`, caches it in state, and draws the paths within an SVG canvas sized to the browser window. The map uses a fixed projection centered over the country.
