Do you make your own dashboard?

Hello All! I would like to get some feedbacks about the problem I found.
I really appreciate if any comments!

But for large datas such as user's click or behaviors, I think it is almost impossible for small projects because there are lots of work needs to be done. ( collecting data, large scale data mining using Spark, Hadoop etc)
