Interactive Dashboard Top Five List

I have a client that would like a widget on their dashboard the lists the top 5 clients by revenue. Compiling the data is one thing, but I don't even think there is a chart/list that would even limit to the top 5, correct? Has anyone else run into this kind of issue in the past? I find clients that are migrating from Salesforce find out dashboards very outdated looking. 

Thanks,

Anthony
