In 'Line chart' add categories for data driven line width and line color range

In a line chart it could be a wish to display more aspects of data. I'm using line chart now to display time-location dependencies. It is my wish to drop a data column on 'width' aspect, as to indicate the load per time and per location in the same diagram.

When a label could be added to the lines, then the color could be available to color-mark critical points in the flow.

Compare this request to flow map, where exactly this is possible. Backwards compatible development in the default visual is possible if the empty aspects continues to show the default behavior.
