Plotly 2.0 is the only choice for a free Community account. The original is not available except with a Pro account, which is now $396 a YEAR, billed annually. This works out to $1.08 PER DAY, for ONE USER. Of course, if you only need it a few days a year, it isn't worth $400.
If it's for a business, then okay. Maybe you'd pay that much. But then you're looking at $948, and that's still for a cloud service.
Want on-premise, behind-the-firewall protection for your data? That'll be $9,950 please, and only for 5 licenses.

one of the fastest charting programs I've tested. It took about 62 ms to chart a line representing 99k pts and rescale the x & y axis. Nice pan and zoom features. Open source.
