Sigh. Datashader is not a paper, it's an actual usable piece of software, so it should be compared to other tools and libraries for rendering data. Unlike nearly ever other 2D plotting library available for Python, it can operate in core or out of core, so it's entirely appropriate to advertise that fact (why hide it?). Unlike OpenGL's point drawing functions and nearly every other 2D plotting library available for Python, it avoids overplotting and z-ordering issues that make visualizations misleading (so why hide that?). Unlike NumPy's histogram2D, it allows you to define what it means to aggregate the contents of each bin (mean, min, std, etc.), to focus on different aspects of your data. It's a mystery to me why you think Datashader should somehow fail to advertise what it's useful for!
