Mastering Grafana Map Markers and Geomaps

QuestDB, an open-source time-series database designed for high-performance workloads, offers ultra-low latency, high ingestion throughput, and a versatile storage engine with native support for Parquet and SQL, ensuring data portability without vendor lock-in. This tutorial explores how to utilize Grafana's Geomap panel with QuestDB to visualize real-time data, using Sydney, Australia's bus data as a case study. The process involves importing CSV data into QuestDB, configuring a Geomap panel in Grafana, and customizing map views and markers to display dynamic information such as bus position, speed, and direction. Through various configurations and queries, the tutorial demonstrates how to manage and enhance map visuals, addressing Grafana's current limitations in plotting multiple routes while suggesting adjustments to achieve desired outcomes.
