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.

You Know the Insights – We Craft the Show
Hours vanish into dashboards and decks, yet the room still asks “So what?” Numbers stay silent, clarity fades, and decisions slide to “later.” Our team puts 50 years of dataviz craft into an animated slide deck you present just like PPT. You guide the clicks; the story moves the room. Vizzu turns your data into a guided, animated story — so instead of sharing static slides or complex dashboards, you walk your audience through the numbers step by step. We built Vizzu from the ground up — and now use it to craft data stories that help you deliver your insights with maximum clarity and impact. Designed specifically for live presentations , Vizzu keeps attention focused and makes sure your…from vizzu.io

Talanoa▲343Hi 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…
