indiaMap experiment

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.

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.

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.

VVamsi Krishna

India Map

This example displays a map of India with each state rendered as a filled green path. It demonstrates the core D3 geo capabilities, using `geoMercator` to project geographic coordinates and `geoPath` to generate the SVG path strings for the map features. The visualization is built with React, fetching GeoJSON data from a GitHub gist and converting it from TopoJSON using the `topojson` `feature` function. The Map component imports these D3 functions to transform the data into the final SVG rendering.

AAshrith Kudidhi

India Map

This example displays a map of India with its states, rendered as an SVG using D3.js v5 and React. The map uses a Mercator projection and colors each state with a purple scale, with state names labeled at their centroids. The visualization relies on d3-geoPath and a TopoJSON file for state boundaries, with a zoom feature available but not activated in the code.

INDIA MAP

This example renders a choropleth-style SVG map of India using D3 v5 and React. It displays the country’s geographic boundaries as light blue filled paths with black borders. The visualization loads GeoJSON data from a GitHub gist, applies a Mercator projection centered on the subcontinent, and uses `d3.geoPath` to convert geographic coordinates into SVG path data. Although React is included in the page, the map is drawn imperatively with D3’s `d3.select` and `d3.json`, without utilizing React components for rendering.

India Map

This choropleth map visualizes the states of India, with each state filled by a distinct categorical color and labeled with its name. The map uses the Mercator projection, positioned and scaled to center the country. The example employs `d3.geoPath` to generate SVG paths from the provided GeoJSON data, leveraging a categorical color scale for fills. State name labels are placed at each region's centroid, and the entire rendering is implemented using D3 v5 within a React-based context.

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.
