Grafana Panel similar for JenniferSoft

Dear all,

Currently Im using Grafana to show a Dashboard with some information of my users access flow. Basically from where they come (Twitter, Facebook, Instagram, etc) and where they go in our services. I want to show it in a similar way that JenniferSoft:

Basically showing from where the users came (left side of the chart), the amount of users processed (middle part) and to where they go (right part).

Is there any visualization currently available that can support this?

Thank you for your support.
