Rendering Incremental Points on Maps with Ruby and Rails January 30, 2026 When working with maps in Ruby or Ruby on Rails applications, most solutions assume that all geospatial data must be prepared upfront — usually as GeoJSON layers. While this works well for static datasets, it becomes inefficient when dealing with event-driven data such…

The libgd-gis library introduces an add_point API for incrementally rendering individual map points in Ruby applications without rebuilding entire GeoJSON layers. Points can be styled as image icons, numeric markers, alphabetic markers, or symbols, making it suitable for event-driven data like sales, API requests, or real-time activity. The approach uses YAML-based styling and provides server-side rendering without requiring tile servers or JavaScript, fitting naturally into Rails dashboards and monitoring tools.
