I have a flowchart or process diagram (i actually don't know what's the correct name) that shows all the steps a customer goes through, from the moment they make a request, until the end of the process. And i want to monitor how many customers i have in each step. For example if today i have 100 customers, 10 could be at the start, 20 in the validation, 30 in hold, 20 in rejected and so on.
I've been looking for diagram tools but all of them focus on drawing the diagram and i want a web app that also displays the numbers "in real time" (we have a database that updates the status every hour). I tryed python dash but it only has a sanky chart but thats not what im looking for.
This is what im working with but is a power point!

Any suggestions of a software or library, or any lead at all?
