What it is and what it does
Branca is a Python library for programmatically generating HTML and JavaScript pages. It wraps Jinja2 templating to let you build complex web content as Python objects rather than writing raw markup. Originally developed as part of the folium project, it now stands alone as a general-purpose tool for anyone who needs to create dynamic web pages from Python code.
The library is designed for data visualization and web content generation workflows where you want to avoid hand-coding HTML and JavaScript. It supports modern Python versions (3.8–3.12) and has no heavy compiled dependencies, making it straightforward to install and use in any Python environment.
Use it for
- Generate interactive web dashboards and visualizations from Python data analysis code
- Create HTML reports programmatically with dynamic content and styling
- Build custom map or chart visualizations that need both HTML structure and JavaScript interactivity
- Template-based web content generation for data science notebooks and Jupyter environments
- Embed interactive elements into static documentation or data export workflows
