Mapv is an open-source JavaScript library for geographic information visualization, built on canvas. It renders large volumes of point, line, and polygon data with styles like scatter plots, heatmaps, grids, and clustering.

Use cases

• visualize large sets of geographic points on a map
• render heatmaps from location data
• cluster thousands of map markers
• draw migration or trajectory lines on a map
• display grid-based density maps of geo data

When to choose

• you need canvas-based rendering of massive geographic datasets in the browser
• you want built-in heatmap, grid, and clustering visualizations
• you work with Baidu Maps or similar JS map APIs

When to avoid

• you need 3D globe or WebGL-level performance (consider deck.gl or mapbox)
• you need server-side or native mobile rendering
• you require a stable, actively evolving API (2.0 is a pre-release with unstable API)
