  • SonarQube - Static code analysis for 29 languages.
  • Scout APM - Less time debugging, more time building
  • OPS - Build and Run Open Source Unikernels
  • GitHub repo perspective

    A data visualization and analytics component, especially well-suited for large and/or streaming datasets.

    The best example of WASM being used to render to canvas (it's also visualizations) I've seen is "Perspective":

      "Perspective is an interactive analytics and data visualization component, which is especially well-suited for large and/or streaming datasets. Originally developed at J.P. Morgan and open-sourced through the Fintech Open Source Foundation (FINOS), Perspective makes it simple to build user-configurable analytics entirely in the browser, or in concert with Python and/or Jupyterlab. Use it to create reports, dashboards, notebooks and applications, with static data or streaming updates via Apache Arrow."

  • GitHub repo graphql-bench

    A super simple tool to benchmark GraphQL queries

    Just went through the examples -- I thought it was really neat!

    Often times I want/need to display data in more than one format. Usually I just take up a bunch of page space by putting multiple charts.

    Here's an example showing what I mean from actual project:

    If there was a solid and comprehensive charting library that could "tween" between the chart formats, only taking up the space of 1 chart, that would be a neat solution!

    Have you found certain pairs/combinations of charts that expose hidden relationships when you display them by animating the data points between them?

  • GitHub repo gemini

    A grammar and recommender system for animated transitions in Vega/Vega-Lite (by uwdata)

  • GitHub repo Vizzu

    Library for animated data visualizations and data stories.

    We have added a markdown file in the repo to list 3rd party projects:

  • GitHub repo SandDance

    Visually explore, understand, and present your data.

    They wrote a great paper explaining their "Unit Visualization" concept/approach:

    IIRC their engine used to be their own in house WebGL code, but according to their GitHub ( they are now using ( for rendering and Vega for chart logic. I do think it's not designed to be used as a library though but a complete studio like environment.
