Good job, your charts look really good. Too bad they aren't interactive, it makes the legend+values mandatory to understand the data. Unless you just want to use them as art.
Also, the pie chart and doughnut charts seem odd. The general rule is to order the values clockwise (biggest piece starts in top middle and extends to the right). It really helps readability and is a convention.
Indeed. I was looking at this hoping to find a way to label pie charts or even have the inner circle of the doughnut chart display the part of the chart I'm hovering over.

Keep up the good work!
