This repository hosts the source code of the paper Rainbow submitted to EuroVis 2022.
We provide a Tutorial to run Rainbow on top of PostgreSQL to visualize 100k synthetic sample tweets data.
Rainbow is a general framework that computes high-quality scatterplots for given result-size budgets. It uses an in-memory rendering-aware index to answer arbitrary zoom/pan queries.
The following demo video shows the effect of using Rainbow to visualize 10 million tweets on a MacBook Pro laptop.
