Use case example: Words in ad headline and click through rate (CTR) analysis

Bubble chart in this example analyzes correlation between number of words in social media ad headline and click through rate (CTR). 

Number of words in ad headline are plotted on X-axis. Click through rates (CTR) are plotted on Y-axis. Bubble are shown at the intersection of X and Y-axis. CTR value determines the diameter / size of each bubble. Larger the CTR, bigger is the bubble size.

As you can see, 5 word ad headlines get highest CTR (25%) and hence the largest bubble size. Ads with 2, 6 and 9 words in headline are among the lowest CTR generators.
