[Talk-GB] FHRS/OSM comparison tool now includes graphs

A lot of authorities exclude up to a third of fhrs records from geocoding. These seem to largely be people trading from home and many social care establishments e.g. refuges from domestic violence.
It's quite plausible that authority practice on this can change.

Thanks for your email. Yes, I'm pretty sure that's how the locations
have been derived in most cases and the comparison tool coalesces nearby
establishments into a single marker position and displays a list in the
popup for that reason.
If the FSA aren't able to solve the problem, I may add another stage of
processing to the comparison tool and look up postcode centroids.
