Timeline chart

[vadimffe]

Thumbs up for Alberto for all the hard work has been done so far. I know current version is still in beta, but it would be highly appreciated to have Timeline chart as a part of this library. To draw an overview of timelines with several sections for each timeline. Also possibility to show or hide Today date as a vertical line.

Here is an example of similar chart: https://apexcharts.com/javascript-chart-demos/timeline-charts/multiple-series-group-rows/

It would be relatively easy to accomplish utilizing current CartesianChart.
