We are working towards becoming experts using graphs and charts. The title is a play on the phrase "art for art's sake". Is there a place where having a chart for its own sake is meaningful?

Interpretation of graphs comes later, but it is worthwhile introducing the idea of comparison - useful for pie charts.
