dojox/charting/widget/Chart doesn't properly use dojo/parser, data-dojo-*

[dylan]

The source code for dojox/charting/widget/Chart doesn't seem to use the parser as expected, so properties defined inline cannot use data-dojo-* appropriately.

For example:

<div data-dojo-type="dojox/charting/widget/Chart" data-dojo-props="theme:dojox.charting.themes.Claro" id="viewsChart" style="width: 550px; height: 550px;">

<div class="plot" name="default" type="Pie" radius="200" fontColor="#000" labelOffset="-20"></div> <div class="series" name="Last Week's Visits" array="chartData"></div>

</div>

Notice that type, radius, array, etc. are specified as custom attributes. Any attempts I've made to embed them in data-dojo-props, etc. fails.

There is code in the chart widget like this: var name = node.getAttribute("name"), type = node.getAttribute("type");

Which shows that while it's inheriting from _WidgetBase, it's not actually using it effectively.

Also, theme names do not work with MIDs, and instead must use the older dot-separate syntax.
