Using the algebraic design framework presented in class, describe one $\alpha$s (transformations in the data) that corresponds to the given $\omega$s (transformation in the visual encoding) in the following scenarios:
a. On a scatterplot visualization, a point moves along an axis encoded by a linear scale
b. On a scatterplot visualization, a point moves along an axis encoded by a logarithmic scale
When visualizing a time series with a line chart, what choices are there besides the choice of scale in the x axis and the y axis, and what are the impacts of these choices?
What are the advantages and disadvantages of using a scatterplot matrix versus using a parallel coordinates plot? Use the perceptual principles discussed in class.
