Ask HN: How Do You Simplify a Complicated Topic?

I'm the founder of a startup in the clean tech and IoT space. We deal with more data than we could possibly use in a user friendly manner. There are literally an infinite number of ways we can utilize this data for our users and convey helpful messages to them. Obviously, we can't do everything. But, when we prioritize, we find ourselves with line charts and column charts that just don't seem entirely user friendly. How do you guys take a really complicated topic and dumb it down so people don't have to "learn" your product? Examples would be fabulous. Thanks!
