What is the best visual tool to track changes over a period of time?
Line graphs are used to track changes over short and long periods of time. When smaller changes exist, line graphs are better to use than bar graphs. Line graphs can also be used to compare changes over the same period of time for more than one group.
How do you visualize data with more than two dimensions?
The best way to go higher than three dimensions is to use plot facets, color, shapes, sizes, depth and so on. You can also use time as a dimension by making an animated plot for other attributes over time (considering time is a dimension in the data).
Which graphing method should you use to visualize a large set of measurements specifically to see distribution and variation?
Scatter charts are primarily used for correlation and distribution analysis. Good for showing the relationship between two different variables where one correlates to another (or doesn't). Scatter charts can also show the data distribution or clustering trends and help you spot anomalies or outliers.
