Embedded our open-source charting lib into a no-code storytelling tool
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. Today, we're proud to introduce our no-code storytelling tool. With this tool, anyone can turn their…
In plain words
Vizzu is a data visualization platform built on a C++ charting engine running on WebAssembly. It offers an open-source JavaScript library for developers to create animated, interactive charts, a Python wrapper for data scientists, and a no-code tool for non-technical users to build data-driven presentations. The platform handles chart creation, interactive data exploration, and storytelling through visual sequences without requiring coding skills.

In the maker’s words, at launch
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. Today, we're proud to introduce our no-code storytelling tool. With this tool, anyone can turn their static data into dynamic, interactive presentations. What Vizzu Does: - Easy Chart Creation — Simply select your data and get chart suggestions. - Interactive Exploration — Identify relationships, trends, and outliers by visually exploring your data. - Data Story Presentation — Create a sequence of slides with animated transitions. Unlike other data visualization tools, Vizzu automatically animates chart transitions, making presentations more engaging and easier to understand. The focus on storytelling and ease of use sets it apart. Try It Out: You can try Vizzu right away by signing up at https://vizzu.io. We'd love to hear your feedback and suggestions!
