[GT] Interactive SVG GT chart

[Chia-liang Kao <clkao AT clkao.org>]

Hi all,

I just published a charting tool for GT with raphaeljs:
http://github.com/clkao/Finance-GeniusTrader-Chart.

In summary, it's a web/svg-based interactive GT chart that allows you
to browse through all the data in DB, with a cursor that shows you the
values for the column you are looking at.  Sorry that I don't have a
demo setup somewhere.

It's still quite rough and a bit slow, but it can already do quite a
bit, including dynamic paging.  look at the javascript in
template/default.html, it's quite similar to how the current
graphics.pl defines zones and graphical objects.  I am going to add
overlays for trade histories from system or csv when i have time.  but
please feel free to hack on it.

warning: this requires a lot of bleeding edge modules, and a modern
browser that supports SVG!

You'll need the CPAN branch of GT (or my cpan-pu branch on github for
better performance), Plack and Tatsumaki from CPAN, after installing
all deps, run:

% plackup -p 3997

and then visit http://localhost:3997/d/TX/day, change TX and day to
some code/timeframe you have in the database.

Cheers,
CLK
