Orientation change to Interactive data visualisation spliter
Typically data sets are oriented to have more rows than columns as it's easier to read. Currently in the cube viewer having the chart take-up the bottom half of the screen means that parts of the data-table are quite often cut-off from view.
This problem would be solved by optionally allowing the splitter to take an vertical orientation, putting the chart on the RHS of screen. Allowing the data-table to extend to the bottom of screen.
In such a mode the default chart would be a horizontal bar type.
