Often we create our own charts, not from the charting engine, but from shapes, text, and graphics. Of course, this is for highly visual presentations that we know are not going to rely on charts with data and can be adjusted for use in other presentations. So, this is as much about animation as slide content styling. Before the animation example, I want to show the design for the nice bar chart. Each bar is comprised of 4 graphic elements: red box with text top aligned, grey box with text bottom aligned, grey outline (no fill box), and a black line.
Here are the animated bar charts (sample video has 2 slides with visual bar charts, client content removed, and for example here only).
