Vizro

Vizro is a low-code, open-source Python toolkit for building production-ready data visualization apps and interactive dashboards with minimal configuration.

Vizro is an open-source, Python-based toolkit designed to create production-ready data visualization applications. It allows users to define app structures using simple configuration files, including Pydantic models, JSON, YAML, or Python dictionaries. The framework supports essential dashboard elements such as charts, tables, KPI indicators, and interactive forms with built-in navigation and grid layouts. For advanced requirements, it offers high-code extensions that permit customization via Python, JavaScript, HTML, and CSS. The toolkit operates on the established dependencies of Plotly and Dash to ensure scalability and visual quality. Additionally, Vizro-MCP provides a Model Context Protocol server to assist LLMs in generating charts and dashboards step-by-step.
