thanks for sharing, but holy slowwww

Exactly what I saw. This isn't a matter of slow server, but some examples are taking way too much ressources. Freezes. In the case of many charts in the scope, as i need refresh every 10 seconds, this will turn in blocking in no time. Testing performances in firefox debugger is already freezing with one chart and no refresh, and i didn't see the garbage collector be significant. (Memory leaks..) Too bad that charts a…

Sorry - early days. Thanks for pointing out. We'll fix them as we go! Soon.

Earlier quoted context omitted.

Interestingly enough, while this is as good as it gets, my initial reaction to domain name was negative. From previous experience I learned that domains like that are taken by squatters or companies that... Well, don't really know how to capitalize on them. Kudos to OP for actually offering something to do with charts! :)

Well - we took it from squatters :) and are trying to turn it into something really useful. That's why looking for feedback on what we've built!

Took it from squatters? Do you mean legal action?

If so. I think this would definitely be worthy of a blog post on exactly how you did it.

Everytime I search for domain names, they are all taken up by squatters who want 5 to 6 figure amounts and they have been sitting on them for more than 5 years, 10 in some cases.

Of course I email them back laughing, but it does mean I have to choose something completely different.

I'm definitely not going to do a snappa.io to snappa.com lol [0].

Checkout https://github.com/vega/voyager

Voyager is a recommendation system based on variables characteristics present in data. User is mostly limited by the offerings of voyegar (same story of https://github.com/vega/polestar ). Vega is descriptive version of d3. We find it hard for debugging and creating complex viz. Vega-lite is concise and more intuitive version of vega though. However Muze was created to start directly from data, creating layout, compo…

Hi, one of the Vega-Lite author here. I'm glad you like Vega-Lite and were inspired by our Infovis paper. Vega-Lite is much more mature than when we wrote the Infovis paper so I suggest you to check it out. Compared to Muze, Vega-Lite is embracing full declarativeness.

how does this compare with fusioncharts ?

FusionCharts is a configurable JS charting library. You choose your chart, define the parameters (highly configurable, though) and then render it. FusionCharts' strength is ease of use, backward compatibility, theming etc.

Muze is data-first. You start with data, apply any operations (if needed), then render. Muze automatically detects the right chart for that and then renders. Also Muze allows you to compose any kind of cartesian visualization, as it follows grammar of graphics.

So if I've to explain this in a spectrum, it goes like this:

d3 (very powerful, high learning curve, you can do anything) Muze (data-first, Grammar of graphics oriented, compose viz) FusionCharts (chart-first, lot of depth in configurations, but can't extend yourself for new chart types)

Hope this helps.

Nice work. I see a lot of potential. Offtopic question, apologies: Where and how one can create the start page animation ( the one in 3D , with the moving impulses and floating charts ) ?

It was a handwritten svg animation with d3 later enhanced using adobe illustrator.

Is there any timeline example? Like http://visjs.org/timeline_examples.html

Thanks for bringing this up. It’s possible to create visualization like this using Muze easily. Will create an example and keep you updated. Should we reach out to you once done (if yes, let me know how)!
