This example demonstrates a heatmap overlay on a dark CartoDB basemap, showing the density of simulated point data concentrated around a central Paris location. The visualization is created with R, using the `leaflet` and `leaflet.extras` packages, specifically the `addHeatmap` function with a fixed radius and intensity. The code generates three normally distributed random samples (500k, 100k, and 10k points) with `rnorm`, but displays only the small sample. The rendering relies on Leaflet’s tile-based map and heatmap smoothing, with point aggregation creating a glowing density surface over the geographic area.

This example visualizes 500,000 randomly generated geographic points centered on Paris as a density heatmap. The code uses the `leaflet` package with the `addHeatmap` function to render the distribution, displaying points over a CartoDB DarkMatter tile layer. Data is synthesized using `rnorm` and sampled into smaller sets with `dplyr`’s `sample_n`. The visualization shows how a large point cloud condenses into a bright core with fading edges, demonstrating leaflet’s heatmap capabilities for large datasets.

This example displays a WebGL heatmap of a large simulated point cloud centered on Paris, using 100,000 generated longitude and latitude coordinates. It shows density distribution through a glowing overlay on a dark CartoDB.DarkMatter tile map. The visualization is rendered with the `leaflet` and `leaflet.extras` R packages, specifically `addWebGLHeatmap`, which leverages WebGL for efficient GPU-accelerated rendering. The data is produced via `rnorm` and `sample_n` from `dplyr`, highlighting performance with large spatial datasets.

This visualization displays a heatmap of simulated GPS point density across Paris, generated from a normally distributed sample of 500,000 coordinates. The map uses the `leaflet` R package’s `addHeatmap` function, which renders point intensity using a radius of 10 and full opacity, over a CartoDB DarkMatter tile layer. The data is drawn from a subset of 100,000 points, plotted via the Leaflet JavaScript library’s heatmap extension. The visualization reveals the spatial clustering of the synthetic data around the city center, with density fading toward the outskirts.

This WebGL heatmap displays the spatial density of 500,000 randomly generated geographical points centered on Paris, using a dark CartoDB basemap. The visualization shows how point density concentrates toward the city center, with the heatmap intensity representing the Gaussian-distributed sample data. The example demonstrates the `addWebGLHeatmap` function from the `leaflet.extras` package, which relies on the Leaflet mapping library and WebGL rendering for GPU-accelerated heatmap visualization, with size and unit parameters controlling the point radius in pixels.

A heatmap of 500,000 simulated points clusters in Paris, displayed as a WebGL layer over a dark CartoDB map. The visualization samples 10,000 points, using leaflet and leaflet.extras to render the heatmap with pixel-based sizes. The data is randomly generated from a normal distribution around Paris's geographic center, and the rendering leverages WebGL for performance. The basemap and heatmap are combined using the `addProviderTiles` and `addWebGLHeatmap` functions.

Leaflet - heatmap

A grid of manually collected coordinates animates into a Leaflet heatmap, gradually revealing clusters of activity around a metro station. The example demonstrates the `addLatLng` method of the Leaflet.heat plugin, which adds points one by one every 200 milliseconds. A styled gradient from blue to red encodes intensity, while the map uses OpenStreetMap tiles. The static dataset, defined as a JavaScript array, is fed incrementally into the plugin’s heat layer, showcasing its redraw behavior without explicit calls.

Heatmap

This heatmap blends a base map with three point locations that are transformed into radial gradients, showing how they are highlighted on a map. The visualization combines a CloudMade tile layer and OpenStreetMap data, with the points loaded as GeoJSON features. The map uses the Polymaps library, and its `load` callback dynamically adjusts each point’s radius based on the current zoom level while assigning a green gradient fill with fading opacity.

Create a heatmap layer

This example creates an interactive heatmap layer on top of a Mapbox dark basemap, using Mapbox GL JS. It visualizes point data from a GeoJSON source, showing earthquake or seismic intensities across the U.S. The heatmap uses color gradients and zoom-dependent intensity, radius, and opacity, transitioning to a circle layer at higher zoom levels. The circles also encode magnitude via a color scale, with a white stroke. The code loads the GeoJSON data from a remote gist URL and applies heatmap and circle layers with interpolation functions.
