This example combines Leaflet.js 0.7.7 with D3 v4 to render a GeoJSON map of Japanese prefectures on an interactive tile-less map. The map is centered on Japan, constrained to a bounding box between latitudes 25–50 and longitudes 112–158, with zoom limits of 5–10. D3 loads the local `ken.geojson` file, which Leaflet then draws as semi-transparent white polygon features using `L.geoJson` with a custom style for weight, opacity, and fill. An invisible rectangle marks the allowed viewing area.

leaflet - Map with D3.js outline

This example combines Leaflet with D3.js to render a geographic map of Japanese prefectures. It displays a GeoJSON polygon of Tottori Prefecture, overlaid on a tile layer from the Geospatial Information Authority of Japan. The code uses Leaflet’s `L.map` and `L.tileLayer` for base tiles, while D3’s `d3.geo.path` with a custom `d3.geo.transform` projection converts latitude/longitude coordinates to screen points via `map.latLngToLayerPoint`. The D3-selected SVG paths are redrawn on Leaflet’s `viewreset` event.

Leaflet.js × D3.js × geojson-vt.js - Clickeble Canvas Tiles Map

This interactive map displays Japanese municipal boundaries using vector tiles rendered onto Canvas elements within a Leaflet.js map. The visualization employs geojson-vt.js to convert GeoJSON data into tile-based vector features, which are then drawn using D3.js for click interaction handling. Each polygon is rendered with a unique picking color, enabling feature identification through Canvas `getImageData` pixel inspection on mouse events. The map supports zoom-dependent styling with adjustable line widths and dash patterns, showing prefectural city data including Sendai and Ora-machi boundaries.

leaflet - Map on D3.js points

This example shows a Leaflet map displaying Japanese land price survey points as red circles over a tile-based base map, with the points positioned using geographic coordinates. The visualization combines Leaflet’s mapping and tile-layer API with D3.js to render the data: D3 is used to select the map’s SVG layer, append a group, and create circle elements from a GeoJSON file. The circles’ positions are updated via `map.latLngToLayerPoint`, which converts latitude and longitude into screen coordinates during map view changes. The example uses leaflet 0.7.7 and D3.v3, loading data from `landprice.geojson`.

Leaflet.js × D3.js × geojson-vt.js - Redraw Canvas Tiles Map

This example shows a slippy map interface using Leaflet.js alongside D3.js to render geographic boundaries from a GeoJSON dataset. Canvas tiles are generated in the frontend, converting vector data into raster tiles on demand. The core function `addCanvasTile` leverages the `geojson-vt.js` `tileIndex.getTile` API to extract features for a given zoom level and coordinate. Drawing occurs directly on HTML5 canvas elements, and the code uses Canvas `getImageData` to enable click detection on rendered polygons, with D3 selection handling mouse events for property feature identification.

Untitled

This example displays a map of Japan rendered as SVG paths, with each prefecture drawn as a black shape outlined in white. The visualization uses d3.geoMercator projection with a clip extent and centers the map at coordinates [140, 30] with a scale of 700. It loads GeoJSON data via topojson’s feature method, applies a categorical color scale, and supports zooming and panning through d3.zoom. The map’s styling and layout are defined in an external stylesheet, and the data comes from a remote gist.

Let's make a JPN map with D3.js!

This example displays a black-and-white map of Japan with prefecture boundaries rendered as white strokes, using the jpn-atlas dataset as its geographic source. It loads the data from a remote JSON file and applies a Mercator projection through `d3.geoMercator` and `d3.geoPath` to generate SVG paths for each prefecture. The code uses `topojson.feature` to convert the TopoJSON into GeoJSON, then binds the features to path elements in the SVG. The visualization demonstrates a straightforward D3 v5 workflow for choropleth preparation.

leaflet - Images on Map (using D3.js)

This example overlays the locations of hot springs in Hokkaido, Japan, onto an interactive Leaflet map. It loads point data from a GeoJSON file and renders each location as an SVG icon, with a tooltip that displays the hot spring name on hover. The code combines a Leaflet tile map with D3.js selections and its `latLngToLayerPoint` method to position icons dynamically during pan and zoom. The map is initialized with a Mapbox tile layer and the icon is a custom SVG file.

leaflet - Markers on map

This example uses the Leaflet mapping library to place interactive markers on a tile-based map of Tokyo. A small CSV dataset provides the station names and geographic coordinates for each marker, which are loaded with d3.csv. The map background is rendered using Mapbox tile layers, and each station marker is bound to a popup that displays its name. The visualization combines Leaflet’s map interactions with D3’s data-loading capabilities to create a straightforward geographic point display.
