In the 2nd bullet point of a paper on graph etiquette;

There are only a few basic types of graphs.
– Trend graphs. If you wish to emphasize the trend in a time series, a line chart (i.e. use a line to connect the data points to show the trend) is better than a series of side-by-side bars.
– Relative size graphs. Here side-by-side bar graphs are best, but all bars must be anchored at zero. All bars should be equal width, otherwise, readers of the graph will be confused by differences in area, rather than difference in lengths of the bars.
– Composition graphs. This is where pie-charts are often (badly) used. The trouble with pie charts is that people are not well programmed to compare angles of pies. A better graph is a segmented bar-chart where the bar (that streches from 0 to 100%) is segmented into pieces. Put the most important segments at the top or the bottom of the bar (so that they are anchored at 0% or 100%) – this enables most readers to accurately estimate the percentage of the bar used by the category

You nailed 2/3 of the very first things they teach you about graphs haha
