Vizzu – Open-source charting library focused on animating charts

In plain words

Vizzu is an open-source charting library designed for developers who want to create animated data visualizations. It enables smooth transitions and movements between different chart types and data states, making it easier to build interactive dashboards and reports. The library is available for integration into web applications and provides tools to animate charts rather than simply displaying static graphics, distinguishing it from traditional charting solutions.

  Embedded our open-source charting lib into a no-code storytelling tool2024 · vizzu.io · ▲13

  Hi HN, We're a small team working on a new dataviz engine and its applications. We built our charting engine in C++ and run it on WebAssembly. Two years ago, we launched Vizzu as an open-source animated data visualization library aimed at JS developers, allowing users to create dynamic charts. We also released a Python wrapper under the name ipyvizzu for data scientists. Since then, we've been working hard to make this technology accessible to everyone, regardless of their coding skills.

  Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…
