Subject Re: working of HICC

Hi Shreya,

I think you are on the right track.  The HICC war file contains a script
called single-series-chart-javascript.jsp.  This jsp script handles all
mechanism of database to JSON graphing string.  However, the database part
is slowly phasing out, and will be replaced with chukwaRecord to JSON
graphing string.
