Show HN: Tableau-like Data Visualization library (free), powered by WebAssembly

The licensing for this is confusing. :(<p>eg:<p><a href="https:&#x2F;&#x2F;muzejs.org&#x2F;muze-wa&#x2F;eula" rel="nofollow">https:&#x2F;&#x2F;muzejs.org&#x2F;muze-wa&#x2F;eula</a><p><pre><code> Reverse engineering: You may not reverse engineer or disassemble the Software. </code></pre> However, there&#x27;s a GitHub repo for it, as if it&#x27;s pretending to be OSS:<p><a href="https:&#x2F;&#x2F;github.com&#x2F;chartshq&#x2F;muze" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;chartshq&#x2F;muze</a><p><a href="https:&#x2F;&#x2F;github.com&#x2F;chartshq&#x2F;muze&#x2F;blob&#x2F;master&#x2F;LICENSE" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;chartshq&#x2F;muze&#x2F;blob&#x2F;master&#x2F;LICENSE</a> &lt;-- same heavily restricted license as above

Hi everyone,<p>A while ago, we had released a Tableau-like data visualization library in JavaScript (original post at <a href="https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=18193264" rel="nofollow">https:&#x2F;&#x2F;news.ycombinator.com&#x2F;item?id=18193264</a>). We got the feedback that it was performing slow because of client-side data operations and rendering. As such, we have released a new version, where all data related operations are now powered by WebAssembly, along with a full design upgrade. It’s at <a href="https:&#x2F;&#x2F;muzejs.org" rel="nofollow">https:&#x2F;&#x2F;muzejs.org</a> - we would love to get your feedback.<p>Like before, it’s a data-first library with its own DataModel, built using Grammar of Graphics approach. Unlike traditional charting libraries, which use a chart-first configuration, Muze allows relational algebra operations on DataModel (in browser). Also, the visualizations are fully extendible through compositions, layers and programmatic hooks - so you’re not restricted by the out-of-box visualizations or default interactions provided by the library.<p>We’ve also built a visual data exploration tool using this (though currently using the JS version, and not WebAssembly; to be upgraded soon), which is at <a href="https:&#x2F;&#x2F;explore.charts.com" rel="nofollow">https:&#x2F;&#x2F;explore.charts.com</a><p>We intend to make these libraries (and UI kits&#x2F;bindings) available for developers to embed within their SaaS&#x2F;internal applications and create Tableau-like interfaces within their application (of which we’ll monetize enterprise-features modules).<p>Would love to get your feedback. Also, what is the next library&#x2F;module that we should build next to make Muze more useful for you?<p>Thanks for taking a look!<p>P.S. We’re working on making our documentation better!<p>Website: <a href="https:&#x2F;&#x2F;muzejs.org" rel="nofollow">https:&#x2F;&#x2F;muzejs.org</a> Visual Data Exploration Tool: <a href="https:&#x2F;&#x2F;explore.charts.com" rel="nofollow">https:&#x2F;&#x2F;explore.charts.com</a> Github: <a href="https:&#x2F;&#x2F;github.com&#x2F;chartshq" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;chartshq</a>

It makes me think of Voyager [1][2], based on Vega and Vega-lite, that leverage a grammar of graphics. A neat trick you can do in Julia is use it interactively to generate plot specs [3].<p>Sadly, looking at the github repo it seems to be unmaintened, so I am glad to see Muze in that space.<p>[1] <a href="https:&#x2F;&#x2F;github.com&#x2F;vega&#x2F;voyager" rel="nofollow">https:&#x2F;&#x2F;github.com&#x2F;vega&#x2F;voyager</a><p>[2] <a href="https:&#x2F;&#x2F;idl.cs.washington.edu&#x2F;papers&#x2F;voyager2&#x2F;" rel="nofollow">https:&#x2F;&#x2F;idl.cs.washington.edu&#x2F;papers&#x2F;voyager2&#x2F;</a><p>[3] <a href="https:&#x2F;&#x2F;youtu.be&#x2F;IJqnx9ShRlM" rel="nofollow">https:&#x2F;&#x2F;youtu.be&#x2F;IJqnx9ShRlM</a>

This looks super cool! I like the fact that, like you said, the focus is on the data and not on preparing the chart configuration stuff. I can definitely use this in my project where I had to write to write an algorithm to parse the data to a valid configuration for ChartJS. I bookmarked this and definitely gonna try it soon. Will let you guys know. My project is also open-source if you wanna check it out <a href="https:&#x2F;&#x2F;chartbrew.com" rel="nofollow">https:&#x2F;&#x2F;chartbrew.com</a>

This seems interesting but I’m not sure how to use it....? We have a react app that could really use a plug and play kind of viz library. Is the idea that I could feed my data into this and it would automatically configure viz based on the dataset it sees?

For Tableau like functionality crossfiltering and drill dowm should be first class features, is that part of the current functionality or is there some exampke?

On my iPhone 11 Pro Max, iOS 13.5.1, chrome 84.0.4147.71 the &quot;health index of each country&quot; is crashing my tab.<p>Otherwise, thanks for sharing. Bookmarked just in case.

This is amazing. Congrats on shipping it Pallav!
