Problem
1. Create ten different versions of line charts for a particular set of (x, y) points. Which ones are best and which ones worst? Explain why.
2. Construct scatter plots for sets of 10, 100, 1000, and 10,000 points. Experiment with the point size to find the most revealing value for each data set.
3. Experiment with different color scales to construct scatter plots for a particular set of (x, y, z) points, where color is used to represent the z dimension. Which color schemes work best? Which are the worst? Explain why.
