Ask HN: I wrote CricketGraph MVP in the browser – should I continue?

One of my favorite apps for the Mac in the late 80's was CricketGraph. I would regularly use it to spice up documents in school - I'm certain it improved my score by a letter grade in certain classes. Since then, charting has been done a thousands times, but I've always wanted to take my run at it:

This version pops up quickly in the browser, supports fun animations and interactive effects, has a built in designer in every chart and runs in browser, on desktop and on server (in JavaScript and Java). I've only got a couple of months invested in it, but with so much competition out there, I don't know how much further I should take it. I'd love to spend years adding many fun new features, but I don't know if there is a way to turn it into a day job.

Any thoughts?
