There is a wealth of charting and reporting tools to use, but in my experience there is also a lot of struggle to build charts that effectively communicate. Since you typically need to put some reports into products and certainly need to use them internally, it’s important to build competence here. Building a general purpose reporting tool is very hard, so many reporting tools make it all too easy to produce a hard to use or accidentally misleading chart. To do better, it helps to pause and think about what you want to show and what basic types of charts can do.
There are some basic types of chart that will solve most of your report-creating needs: Line, Histogram (AKA Bar), and Pie (or Donut). Area (possibly Stacked) is a nice variation on Line, but not strictly necessary.
Pies and Donuts take a lot of heat from the data visualization community, and for pretty good reason. Let’s leave aside the subtle stuff though, there’s a couple of simple rules to follow for making sure you use them properly. Note that any time you have a Pie, a Histogram or Stacked Area could have done the job too.
