Most apps today employ data visualization inappropriately and ineffectively. This is because they were designed by graphic designers and use experience experts. Unfortunately, however, these individuals do not have the practical expertise nor the academic knowledge required. Ultimately, their work looks pretty but communicates little. This is unfortunate, as many apps with good potential eventually fade into obscurity because they didn't employ data visualization principles based in research.
Chances are, if you're looking at this right now, you need a data visualization consultant. Luckily, the principles aren't hard to understand. However, I will tell you honestly whether something doesn't work. So if we talk, please be prepared to accept what I say--I won't blow smoke simply because you're excited about your own work. Most data visualization apps fall short because they pursue flash over substance. That doesn't have to be your app--and it won't be, so long as you use a data visualization consultant to test whether your work can do what you believe it can.
