What is Bokeh?

Before diving into the specifics of version 2.3.3, let's briefly contextualize the library. Bokeh is a powerful Python library for creating interactive and scalable visualizations for modern web browsers. Unlike static plotting libraries (e.g., Matplotlib), Bokeh generates visualizations as HTML/JavaScript applications. This allows for:

• Interactive tools (pan, zoom, select, hover).
• Real-time streaming data.
• Large dataset handling via downsampling and WebGL.
• Seamless integration with web frameworks like Flask and Django.

Bokeh sits comfortably between low-level visualization tools and high-level dashboard frameworks like Dash or Streamlit, offering granular control without writing raw JavaScript.

9. Known Limitations in 2.3.3

• No WebGL for large datasets (added in 3.x).
• HoverTool tooltips limited with ColumnDataSource transformations.
• No bokeh.transform factor_cmap() for categorical color mapping without extra steps.
• Slower rendering for 100k+ points compared to later versions.

Overview

Bokeh 2.3.3 is a maintenance and bugfix release in the stable 2.3.x series of the Bokeh visualization library. This version addresses several critical issues related to data handling, user interface interactions, and documentation accuracy. It does not introduce new features or breaking API changes, making it a safe upgrade for users on any prior 2.3.x release.
