year 4 4.45 5.59 5.5 5.41 5.01 4.72 4.78 4.79 4.82 4.92 5.06
year 5 4.51 5.65 5.62 5.49 5.12 4.8 4.88 4.82 4.95 5.12 5.22
which chart would be suitable for gaining insight on the months and years that had the highest average distance traveled?
a. pie chart
b. heat map
c. scatter chart
d. bubble chart

Explanation:

A heat - map is ideal for visualizing two - dimensional data, such as the relationship between months and years in terms of the average distance traveled. A pie chart is used for showing proportions of a whole, a scatter chart for showing the relationship between two variables, and a bubble chart for showing relationships between three variables. Here, we want to see the variation across months and years, which a heat - map can effectively display.

Answer:

B. Heat map
