Best for

✓ Best for

Developers working on real-time data visualization projects who need high-performance GPU rendering.
Researchers and scientists requiring interactive visualizations for large datasets.

✓ Best for

Projects requiring high-performance interactivity over large datasets
Web applications that need to visualize streaming data
Developers who want to create interactive plots and charts for web apps without a backend service

Not ideal for

✕ Not for

Projects that require cloud-based or web-hosted visualization services.
Applications needing support for multiple programming languages beyond Python.

✕ Not for

Teams needing real-time streaming (Bokeh is more suited for batch processing)
