Creator of Polychart here. We're group of graduating students in University of Waterloo, committed to make visualization and interacting with data easy.

We're trying to tackle this idea from the practical user perspective and theoretical perspective. There are a lot of things to learn from existing systems such as R, Matlab, Maple, Tableau, and Excel. We're also trying to incorporate a lot of ideas from the data visualization community.

We're still very young, I would gladly accept comments and feedbacks from HN community.

Data exploration like this is very interesting, and a problem that's far from solved - so I'm excited about this.

A small UI nitpik: one thing that struck me from the video demo was that your drag targets were on the opposite side of the screen to their source. That seemed a little less discoverable and more involved to use than if they'd been closer.

Does anybody want to share MD5 hash of the file? I'm trying to decompress this file, and I'm keep getting an error.

wait, the torrent link has it. I do have the same md5hash, and yet, it's keep crashing whenever i'm trying to uncompress this shit... wtf is going on.

Did you figure out how to get this working? I tried 7-zip as well as winrar and both errored out

Hey guys, what would be the most sane way to work with this dataset? If it's 173GB, it's probably hard to load it up in a single machine.

Not mine... Sigh.
