Migrate from old dashboard: Visits Charts

[gosso22]

The whole section named Visits Data in the old dashboard here Old dashboard link needs to be migrated. The charts seems to be duplicated so we need to implement this in such a way that you can filter the visits charts by client type. Also this could be in its own tab in superset. @issyzac and @nKataraia - I am tagging you both for this item. It requires a bit of thinking and brain storming.
