The interaction model is something that very few charting libraries have. Also we try to make Polychart.js very easy to get started in, so that creating a simple line or bar chart would take minimal amount of code. Vega is amazing as well for how flexible it is.

We'll be reviewing the licensing option per feedback from HN. Please send a note to [email protected], would love to hear more about what you think would be reasonable :)

Thanks for the feedback. We'll be reviewing the pricing model per the comments from HN. Would love to hear more on what you think would make sense :) [email protected]

Agrees with you that Raphael is very awesome. A difference between Polychart.js and NVD3 is its flexibility: the way one can overlay charts, or even plot any change in polar coordinates. (We took a lot of ideas from R and ggplot2, something data scientists use).

We share your love with d3 also, which unfortunately will not ever work in IE. So until the rest of the world catches up... ;)

Thanks fourm for the feedback! Let us know what you think would be reasonable and email [email protected] for a discount for HN users. (And of course, always free for non-commercial use)

Thanks JangoSteve for the feedback. Would a per application or per domain licensing be something you'd be looking for?

polychart.js makes it really easy to create charts that interacts with one another
