Use case example: Average cost per lead and conversion percentage

The chart in above example shows eight lead generation sources, average cost per lead (represented by columns) and lead conversion rate (percentage) for each source (represented by line chart with data labels).

With a quick look at the chart, audience can see that trade conferences and discount promotions are converting well followed by partners and referrals. While social media is generating leads at lowest cost, the conversion rate is way too low as compared to other lead generation sources.  

It would be interesting also to analyze high, low and average cost per lead by lead generation source.
