Y axis normalization

[Wibo]

Thanks for this fascinating application.
the axis should be normalised to all traffic...percentage of all
google traffic or perhaps categorized traffic.
This way you prevent the typical dip around XMAS that is caused by
people not using their computer and not a dip in popularity of the
subject.
Perhaps an automatic classification of the trend like growth, decline
or over the hill could be made.
search requests that are made from the office and from home appear to
have opposite trends around the holiday season.
