radius_mean gives the average size of the cells in terms of the radius of circles drawn around each cell in the biopsy. texture_mean provides the amount of variation in light to dark values in an image of the cells. sb.regplot (data = cancer, x = "radius_mean", y = "texture_mean", "lowess = True, line_kws = {"color": "orange"}) --INSERT-- 40 texture_mean 35 20 15 10 10 15 20 radius_mean 25 Provide a brief explanation of what is displayed in this plot. Be sure to comment on the orange line and how it expresses the conditional mean of "texture_mean" for different values of "radius_mean."
