I hate the charts produced by programs like Excel, and so am intrigued by a new product from the Omni stable — the GraphSketch tool. The blurb claims that it:

helps you make elegant and precise graphs in seconds, simply by sketching what you want. Specifically designed for reports, presentations, and problem sets where you need to produce sharp-looking graphs on the fly, OmniGraphSketcher combines the data plotting power of charting applications with the ease of a basic drawing program.

I’ve just downloaded it and it works as advertised. Only runs on Macs, I’m afraid.
