H5Web: React components for data visualization and exploration

Demos DOI

H5Web is a collection of React components to visualize and explore data. It consists of three packages:

  • @h5web/lib: visualization components built with react-three-fiber.
  • @h5web/app: a component to explore and visualize data stored in HDF5 (or HDF5-like) files, and data providers to connect this component to various back-end solutions.
  • @h5web/h5wasm: an additional data provider that can read HDF5 files straight in the browser.

While H5Web was initially built with the HDF5 format in mind, @h5web/lib visualization components are not tied to HDF5 and can be used to visualize data from any source. Also, @h5web/app lets you write your own data provider and can therefore work with any other hierarchical data format.

If you're after a ready-made solution to view local HDF5 files, take a look at myHDF5, at the Visual Studio Code extension or at the JupyterLab extension.

NPM packages 📚

H5Web's component library, which includes the main visualization components (LineVis, HeatmapVis, etc.) as well as some of their lower-level building blocks (VisCanvas, ColorBar, etc.)

The library is documented in a Storybook site accessible at https://h5web-docs.panosc.eu.

Some examples of usage of @h5web/lib:

HDF5 viewer component (App) and built-in data providers.

Data providers are components that fetch data from HDF5 back-end solutions and provide this data to the app through React Context. H5Web currently includes three providers, two of which are available in the @h5web/app package:

This package includes two additional data providers, H5WasmLocalFileProvider and H5WasmBufferProvider, that can read HDF5 files straight in the browser thanks to the h5wasm library.

Demos

The demo app demonstrates the use of the built-in data providers and visualizations. Several demos are available, one per data provider:
