Custom visual tool-tips for line chart

If you need to show a tooltip for dots you should render the dots first.
Please used d3.data method to bind data to each dot. Each data point must contain tooltip data that you want to show.
After that you need call addTooltip as you do in the code but the first argument must represent d3.selection for dots.

We don't have any sample custom visual that implements tooltip for line chart.
It seams you should detect cursor position and get data that is related to mouse position. After that, you should send data to Tooltip API.
