In a dashboard, can you help me with the HTML, CSS and Js for displaying a single number in a bubble chart?

[sandeepmakkena]

I am trying to display number of events by day, number of events of each day in a bubble chart where bubble size depends on the date( most recent will be big and oldest will be the smallest). I am really not sure how to get it, Please help.
Thank you.,
