all of the issues/suggestions raised so far.
    If there are no other issues/suggestions we're hoping these can be

Re the others:
- For #3 the code is 'functional' but more time is required to discuss &
determine the best/default user-interface/interaction.
- For #5 think we all agree to defer this ... too many issues still need to
be resolved
- For #6 we're currently looking for valid sources for the map shapefile
data .. sources whose terms&conditions our legal team will approve so we're
all covered.

title position in theme.
*patch uploaded*

#9 label shortening: http://bugs.dojotoolkit.org/ticket/11631
Add customize trailing symbols and rename the "maxLabelWordCount" to
"maxLabelCharCount", there will be a tooltip when you hover on the truncated
About "add a general way to provide already abbreviated tick labels", seems
there is no rule to follow, even the month of the year: "Sep" for
"September", the day of the week: "Mon" for "Monday", user can also
abbreviate "September" to "Sept", "Monday" to "MD". I suppose it's better to
let user customize it in "labelFunc".
*patch uploaded*

#10. Spider Chart: http://bugs.dojotoolkit.org/ticket/11686
Rename the "Radar" chart (Radar.js, dojox.charting.plot2d.Radar, ...) as
"Spider" chart, and provide desciption of this Spider chart and its
application area in the test case of Spider chart, and the differences when
compared to the Radar (Polar) chart.
*patch uploaded*

#11. Gantt chart with Resource chart:
Follow eugene's comments:
1> Make it a top-level name: dojox.gantt.
2> Separate off the css style code in js files into css files.
3> Add some dijit form widgets and use claro theme for better outlook, then
shrink the gantt chart code to less than 250 Kilobyte.
4> change gantt data format from xml to json (adam suggest)
*patch uploaded*
