Bokeh
Bokeh is an interactive visualization library for modern web browsers that enables developers to create elegant and versatile data visualizations in Python. It provides high-performance interactivity over large or streaming datasets and can output to various formats, including HTML files, Jupyter notebooks, and server applications. The library is designed to make it easy to build complex statistical plots, dashboards, and data applications with minimal code.
Developers should learn Bokeh when they need to create interactive, web-based data visualizations for data science, analytics, or reporting purposes, especially in Python environments. It is ideal for building dashboards, real-time data monitoring tools, and exploratory data analysis applications where user interaction (e.g., zooming, panning, hovering) enhances insights. Use cases include financial analysis, scientific research, and business intelligence where dynamic and shareable visualizations are required.
