Display large chart inside a card in a Dashboard

I'm going to design a Dashboard, I know how to show the information but my client said to me that a cohort chart is going to have a lot of information. I wonder if it's ok to add to the card that contains the chart an arrow to expand the chart on another page and there add a link to go back to the dashboard or what is the best way to do this (when we need to show more information for each card). Thanks!
