This is my first project in React.js and it was really nice to work with.

The only part I struggled with was while building the table editor. I'm using contentEditable there and apparently React doesn't play well with it. The virtual DOM gets out of sync after user input and you have to manage it manually.

I really enjoyed making this and I'm happy to hear any feedback about ways to improve it! :)

Just so you know, there are very few situations where one should produce a graph from a set of points by spline interpolation (at least in the natural sciences). It almost never is the right choice, if you don't have a model for how the graph you are sampling looks like you shouldn't draw lines between points at all.

I browse with cookies and localStorage disabled by default (I whitelist sites I need to log into). Your site just comes up blank for me... maybe it requires localStorage for some reason? Not sure why it would, but at least you might want to display a message indicating such.

oh, it uses localStorage to store your chart data so that you can refresh the page and you won't lose your changes.

But you are totally right that it should not be requirement. I will fix that today. Thanks for letting me know!
