Title: Add bar chart to show transaction volumes over time

Add new bar chart module for transaction volumes over time. This is called the "bar_chart_with_number" module, since that is what it is.

As part of this story:

* Fix a few bugs in our graph and view code.
* Refactor existing journey code to create new shared bar chart code, from which
both the journey module and the new bar_chart_with_number module now inherit.
* Create the new module.
* Add tests for untested existing code.

Henry has seen the completed module, and okayed it from a design point of view.
