Creator of Polychart here. We're group of graduating students in University of Waterloo, committed to make visualization and interacting with data easy.<p>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.<p>We're still very young, I would gladly accept comments and feedbacks from HN community.
