The project's actual homepage is better and includes live examples: http://gionkunz.github.io/chartist-js/

Why is canvas considered "wrong technology for illustration"?

I don't believe it's necessarily the wrong tech for illustration... but SVG is maybe a more natural fit for graphing simple shapes like lines, bars, and circles... Also, Adobe Illustrator exports vector graphics which easily map to SVG and can even be exported directly to SVG. Additionally, the SVG makes it easier to attach event handlers to nodes within a graph so you can support mouse/touch interaction simply using the addEventListener... That said, canvas is closer to the pixel so you could implement vector graphics in canvas.

In my experience, SVG is the overall better fit for graphing, but canvas is much faster. I have a use case that requires plotting over 10,000 data points and the only free libraries that I've found that can do this quickly are canvas based ones.

I would like to know how it compares to other graphing libraries. I am one of the current main contributers of Morris.js[1]. I really like some of the things this tackles. However, one of the main things I noticed missing is that there is no way to show the actual value of a point in the graph.

Looks really great. If you've tried to make a responsive chart in D3 then you know why this is useful.

While it looks really nice, there is no way I could submit/deploy a project with that kind of licence bundled in the source code.

Guess you could just change the name etc but that's not really the point!

If one of the corporate legal team picked up on this there would probably be a small shit storm following!

If that really is the only barrier to using this then I'm sure a simple email to the sole copyright holder asking for an MIT/BSD/etc license to the code would solve your problem.

The author put together what looks like a nice library, let's not make an issue out of something so trivial to solve.

Those moving points really got me. Gotta look tonight (Github blocked @ company sigh)

Tech company or... Wouldn't be able to imagine not having access to Github

Looks good, but I wish we could drag the points :(

why does a user need to move points in a chart?

"Actually last quarter's sales were..." <DRAGS POINT>

Maybe he has a use case where the user DOES need to move points? Example a UI allowing a user to set and forecast next quarters sales while visualizing the last.

Well, I could point out several use cases but my specific one is: A time x space graph for tracking movement of vehicles where sometimes the user has to change the positioning of a GPS point that is not to his liking in a planning perspective.
