hvPlot and Panel: Powerful data visualization, exploration, and apps (Room HSEC 4-103/5)
James A. Bednar

This tutorial will show you how to use the Pandas, Dask, or Xarray APIs you already know to interactively explore and visualize your data, even if the data is gigabyte or petabyte sized or is in non-columnar scientific formats such as multidimensional arrays, networks, or unstructured grids. As soon as you have something you like, you can then share a live app as HTML+WASM or backed by a live Python server, by simply replacing your expression arguments with widgets so that users can explore it on their own. These tools let you focus on your data rather than the API, and let you build linked, interactive drill-down exploratory apps without having to run a web-technology software development project, which you can then share without becoming an operations specialist.
