This example displays a choropleth-free map of Japan’s prefectures, using skyblue fill and red strokes to delineate administrative boundaries. Built with D3.js, it employs `d3.geoMercator` projection, `d3.geoPath` for path generation, and `d3.zoom` for interactive pan and zoom. The geographic data is loaded from a TopoJSON file via `topojson.feature`, and `d3.scaleOrdinal` assigns categorical colors. The SVG-based visualization renders state-level polygons from the `JPN_adm1` layer.

ICE 8 - Avinash Chinta - Japan Map

This interactive map displays Japan’s prefectures as green filled paths with white borders, rendered in SVG using React and D3. The code loads GeoJSON from a GitHub gist and applies a Mercator projection via `d3.geoPath` and `d3.geoMercator`, with a zoom behavior enabling pan and zoom transforms. Prefecture colors come from `d3.scaleOrdinal` and `schemeCategory10`, though the applied fill is overridden by CSS. Topojson’s `feature` extracts administrative boundaries from the source data.

Japan Map

This visualization displays a choropleth map of Japan’s administrative regions, with each prefecture filled in a uniform red color and separated by white borders. The map uses an equirectangular-like Mercator projection via `d3.geoMercator` and renders geographic features with `d3.geoPath`. The code loads TopoJSON data for both states and districts, then applies `d3.scaleOrdinal` with a category color scheme, though only the state layer is drawn. Interactive zoom and pan are supported through D3’s `zoom` behavior, which transforms the SVG group containing the map paths.

Japan Map

This map of Japan displays the country’s administrative boundaries as solid blue regions. Built with D3.js, it uses `d3.geoMercator` for projection and `d3.geoPath` to render geographic features from TopoJSON data. The map supports interactive zooming via D3’s `zoom()` component, which dynamically transforms the SVG group containing the paths. The visualization loads geographic data from a remote JSON source, applies a categorical color scale (`d3.scaleOrdinal`), and styles the regions with a blue fill and white stroke.

Japan Map

This choropleth map of Japan displays its administrative regions in warm red-orange fills against a white background. The visualization uses `d3.geoMercator` for projection, `d3.geoPath` to render geographic features, and `topojson.feature` to convert TopoJSON data. It supports zooming through the D3 zoom behavior, with pan and scale applied to a grouped SVG element. The map is built with React and rendered as SVG, using data loaded from a GitHub Gist.

Fork of Japan Map

This example presents a zoomable choropleth map of Japan’s administrative regions, rendered as SVG paths filled with distinct colors from a categorical scale. Using D3 v5 and d3-geo-projection, it applies a Mercator projection clipped to the viewport, with pan and zoom enabled via d3.zoom. Geographic boundaries come from TopoJSON data (JPN_adm1), processed with topojson.feature and drawn using d3.geoPath. The map highlights each prefecture uniformly, with white strokes separating regions.

Fork of ICE8 map of Japan

This example displays a map of Japan rendered as a single brown SVG path with black borders against a light blue background. It uses d3.json to load country boundaries from the world-atlas TopoJSON dataset, filters the features to isolate Japan, and projects the coordinates using d3.geoMercator with a custom translation. The d3.geoPath generator then converts the projected geometry into SVG path data, while topojson.feature extracts the GeoJSON from the TopoJSON structure.

Japan Map

This map of Japan displays its prefectures as semi-transparent purple regions, with each area labeled by its name. The visualization uses `d3.geoMercator` for projection and `d3.geoPath` to render GeoJSON features from a TopoJSON source of Japanese towns. A sequential color scale, `interpolatePurples`, shades each state based on its position in the dataset, while text labels are positioned using `pathGen.centroid`. The map is rendered as SVG and supports zooming via D3’s `zoom` behavior.

Fork of Japan Map

This example displays a choropleth map of Japan’s prefectures, rendered as SVG paths with a uniform orange fill and white strokes. The code loads TopoJSON data twice via `d3.json` and uses `topojson.feature` to extract administrative boundaries. A `d3.geoMercator` projection with `d3.geoPath` draws the geography, while `d3.scaleOrdinal` and `schemeCategory10` are available for potential color encoding. The map supports pan and zoom through `d3.zoom`, transforming a grouped `<g>` element.
