So some suggestions that will aid a startup entrepreneur archetype:
1) How can visualising data help increase my KPI at various stages. I suspect not so much for a pre product market fit company but thats something for you to think about.
2) Instead of hiding the samples behind your main column, bring them to the front.
I remember watching video on TED about this journalist turned data visualisation evangelist a while ago. You won't happen to be him would you? :)
