Use Python and the HSTravel data to answer this question.

You are interested in relationships between specific characteristics in the data and elect to visualize these relationships by creating the appropriate plots.

a$)$ Create a plot of distance vs$.$ travel time. What can you infer from the plot?

b$)$ Create a plot of household size vs$.$ income. What can you infer from the plot?

c$)$ Create a plot of household size vs$.$ number of vehicles. What can you infer from the plot?

d$)$ Are there any additional plots that would serve useful? Are there any subsets of the data that would provide some additional insight if you were to create specific plots considering these subsets?
