Spark DataGrid Help

Question

Where does one look to find examples on the Spark DataGrid? I know its bleeding edge but I can't find much info on how to use it.
Specifically, I have two arrays: One with the column data such as [['name', 'string'], ['age', 'int']] and another with row data, such as [[dave, 30], [ray, 29], [jason, 25], [sara, 30]].
I'd like to have a datagrid bound to these arrays, but not sure how. I'm building a dynamic data browser and it would help to have some info around setting columns dynamically. I played around with creating one array, and giving it objects such as columns, and rows with the data outlined above. Thats not helping either.
THanks for any direction,

Thanks Peter,
I should have been more clear the data/arrays that I am using are brought back from a separate class asynchronously:
var tableName:String = event.currentTarget.selectedItems[0];
tableMap[tableName] = {};
controller.getTableInfo(tableName, function(data:Array):void
tableInfo.source = data.map(function (element:RowData, index:int, array:Array):String {
return element.getColumnAsString(1) + " (" + element.getColumnAsString(2) + ")";
tableMap[tableName].label = tableInfo;
dataGrid.columnHeaderBar.labelField = "label";
controller.selectAll(tableName, function(data:Array):void
tableMap[tableName].data = data;
dataGrid.dataProvider = new ArrayCollection(tableMap[tableName].data);
Right now I am close, but the column headings all say [object GridColumn]
thanks
