Useful leaflet and map sipets

leaflet example

This example shows multiple datasets overlaid as circles on an interactive Leaflet map, with each dataset visualized using a different scale type. It uses the Leaflet library for map tiles and layers, while D3 v5 parses CSV data embedded in `<aside>` elements and binds it to SVG circle markers. The code assigns numerical or categorical attributes to color scales (threshold, quantize, or ordinal) and renders a legend for each group. Map layers for streets, satellite, and grayscale are togglable, and tooltips display an optional address attribute from the data.

Leaflet - MapTiles

This example shows a full-screen interactive map that allows the viewer to switch between dozens of different tile layers, ranging from satellite imagery and street maps to terrain, watercolor, and dark matter styles. The code uses the Leaflet library to render the map and manage layer switching, while pulling tile URLs and attribution strings from the viz.js `viz.leaflet.tiles` API. It includes base layers from providers such as OpenStreetMap, Thunderforest, Stamen, Esri, and CartoDB, demonstrating how to assemble a multi-provider tile switcher in a single HTML page.

Simple Leaflet Map

A simple interactive map displays a geographic area centered on a set of coordinates, with a single red polyline overlaid on base tiles from OpenStreetMap. The map is created with Leaflet, using its `L.map` and `tileLayer` APIs to render the tile background. The polyline, defined as an array of latitude and longitude pairs, is added with the `L.polyline` API and styled with options for color, weight, opacity, dash pattern, and line join. The example demonstrates basic Leaflet map creation and vector overlay customization.

Simple Leaflet Map

A simple interactive map centered on London demonstrates core Leaflet capabilities. The map displays OpenStreetMap tiles and includes a marker with a popup, a red circle, and a polygon, each bound to popups. Clicking anywhere on the map generates a popup showing the clicked latitude and longitude. The example uses the Leaflet JavaScript library and its `L.map`, `L.tileLayer`, `L.marker`, `L.circle`, `L.polygon`, and `L.popup` APIs to build the visualization.

Leaflet Map Example

This example shows a Leaflet map with interactive markers and a circle overlay, plotting applicant counts per country from a CSV dataset. Using the Leaflet JavaScript library, it renders an OpenStreetMap base layer and adds markers for each data point, binding popups to display country-specific information. The code also demonstrates adding a styled circle geometry to the map, and it imports utilities from TopoJSON for potential geospatial operations.

Simple Leaflet Map

This example shows an interactive map centered on Wellington, New Zealand, with a choice between two base tile layers. It uses Leaflet.js to render map tiles and handles layer switching via a control widget. The map includes an OpenStreetMap tile layer and a Thunderforest landscape layer, with proper attribution for both data sources. The code initializes a map element and uses `L.tileLayer` and `L.control.layers` to manage the selectable background layers.

Leaflet.draw Plugin

This example shows an interactive map with the Leaflet.draw plugin, demonstrating drawing and editing tools for polylines, polygons, rectangles, circles, and markers. The map renders OpenStreetMap tiles, with drawn shapes styled in distinct colors and a custom green icon for markers. The code uses Leaflet’s `L.Control.Draw` with options like intersection prevention and area display, and stores created layers in a `L.FeatureGroup` for editing and removal. A custom `L.Icon` class defines the marker appearance, while the `draw:created` event adds new geometries to the group.
