In plain words
TauCharts is an open source JavaScript charting library built on D3.js for data exploration and analysis. It offers a declarative API to map data columns to visual properties, faceted exploration across data segments, and built-in features like trendlines, annotations, and PNG export. Designed for developers, it provides flexibility to customize design and user experience to match specific project requirements.

What we love is that you can adapt design, ux, ui and product requirements according to your own needs. I would also want to pay our respect to TauChart’s team for great support and personal care.

A gallery of graphs built with React and D3.js2023 · react-graph-gallery.com · ▲297Many JS libraries exist to build graphs on the web (Vega, chartJS, Plotly...). They allow to make charts quickly.

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…
