Essay
I used the mouse weights dataset, and created a dot plot with a smoothed line. The graph compares the mice’s wight in grams with their percent body fat, and is separated by male and female mice. I first tried creating the graph by filtering for a specific generation, but I decided to use the whole dataset because I enjoyed being able to see the bigger picture. The female mice clearly present a trend of higher body fat percentages, and an average higher weight than the males. There is also a direct relationship between an increase in body fat, and an increase in weight.
