What is HoloViz?

HoloViz provides high-level Python tools that are designed to work together to solve the entire problem of visualization, from conducting exploratory data analysis to deploying complex dashboards.

The core HoloViz projects are:

• Panel: Create interactive dashboards in Jupyter notebooks or standalone apps
• hvPlot: Quickly and interactively explore data with a familiar API
• HoloViews: Visualize while you analyze by declaring data properties
• GeoViews: Extend HoloViews for geographic data
• Datashader: Render big data images in a browser
• Lumen: Construct no-code dashboards from simple YAML specifications
• Colorcet: Plot with perceptually based colormaps
• Param: Declaratively code in Python
