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.

Japan Map

This visualization displays a map of Japan using D3.js, with each prefecture rendered as a green path. The map uses a Mercator projection with zoom and pan interaction enabled via D3’s `zoom` behavior. TopoJSON data is loaded and converted to GeoJSON using the `feature` API, then paths are drawn with `d3.geoPath`. The code leverages `d3.json` for data loading, `scaleOrdinal` and `schemeCategory10` for potential color scaling, and the `d3-geo-projection` library for projection support. The SVG output is styled with CSS.

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 Country

This map of Japan renders land areas as aquamarine shapes with black outlines, using a Mercator projection. The visualization uses topojson data fetched from a GitHub gist, with TopoJSON APIs (`topojson.presimplify`, `topojson.feature`) for simplification and conversion to GeoJSON. It applies D3’s `d3.geoTransform` to filter polygon details based on a threshold, which is adjustable via a range slider, and draws paths with `d3.geoPath` onto an SVG canvas. The map redraws dynamically when the slider changes or the window resizes.

Japan Country

This interactive map of Japan visualizes geographic regions as SVG paths, rendered with the Mercator projection. Users can adjust a range slider to simplify the map topology in real time, controlling the level of detail through a custom geoTransform filter that removes small areas. The visualization is built with d3.js v4, the topojson library for converting TopoJSON to GeoJSON, and d3.geoPath for generating path data. Hovering over a region displays its name in a tooltip and highlights it in light green.

Fork of Japan Map

This map of Japan displays its prefectural boundaries as distinct orange regions against a white background. Built with React and rendered as SVG, it uses D3’s `geoMercator` projection and `geoPath` to draw the shapes, while `d3-geo-projection` extends the available projections. The visualization supports zooming via D3’s `zoom` behavior, and prefectures are colored using `scaleOrdinal` with `schemeCategory10` for categorical distinction. State boundaries come from TopoJSON data loaded from external GitHub gists, and the page includes CSS for styling.

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 Japan Map

This example visualizes Japan’s administrative boundaries using a Mercator projection rendered as SVG paths. The map displays prefecture outlines in pink with black strokes, colored via d3.scaleOrdinal and schemeCategory10, and supports pan and zoom through d3.zoom. Data is loaded via d3.json from a TopoJSON file, converted to GeoJSON with topojson.feature, and drawn using d3.geoPath. The code imports d3 modules for selection, projections, scales, and event handling, while d3-geo-projection.v2 is included for additional projection support.
