Have you ever had this experience: Python opens a plotting window, and as soon as the data volume increases, it lags like a PowerPoint presentation? Either the rendering is slow, or the interactive experience is terrible.
For scientific visualization at this scale, where data volumes skyrocket and real-time performance is critical, relying on CPU serial plotting just won’t cut it. Enter GPU-accelerated graphics libraries, and fastplotlib is one of the dark horses among them.
What’s the pain point?
CPU plotting: Vector or raster graphics hit memory or rendering bottlenecks as soon as data volume grows.
Interactive lag: Dragging, zooming, or real-time updates with low frame rates feel like driving a tractor.
Slow prototyping: Researchers and algorithm engineers testing new ideas spend half a day just on rendering and visualization tweaks.
Multi-platform adaptation: You write a PyQt demo, but switching to Jupyter Lab or GLFW requires rewriting window management and event callbacks.
