Add HPIs line graph

Working line graph for HPI

Is the date end point incorrect? In the data I believe the last months starts in august (not ends). Should it go to this point?

Is month the correct period? Would quarter be better? Should we use a longer range of time?

Is the copy correct? The current copy is roughly taken from the single stat and deviations stories originally intended to display this data.

is order of visualisations correct?
