  * Setup chart date range controls and all charts
  *
+ * For each chart, a clone of the $chartTemplate are inserted into the document,
+ * and these inserted copies are passed to `new {@link jarmon.Chart}()`.
+ * Therefore, the $chartTemplate should have elements matching the same
+ * selectors documented there.  However, in addition to those, it is useful to
+ * have elements matching these selectors:
+ *
+ * - `input[name=chart_edit]` (optional) : A button to be clicked.  If present,
+ *   when clicked, the graph-legend will turn in to a {@link
+ *   jarmon.ChartEditor}, allowing the user to edit the chart's recipe.
+ * - `input[name=chart_delete]` (optional) : A button to be clicked.  If
+ *   present, when clicked, the graph will be removed from the UI.
+ *
  * @todo Figure out how to allow `$chartTemplate` to be an HTML5 <template>
  *      element.
