Is your feature request related to a problem? Please describe.
Currently, we have a custom swim lane visualization in the Kibana ML plugin that covers a particular use-case for anomalous data over time.

Besides, there is an external kibana-swimlane-vis plugin supported by @peteharverson which a user can install with Kibana up to 7.6.2 version to plot any metric data over time with some customization available. As our current Anomaly swim lane visualization requires some re-work and kibana-swimlane-vis can't be used with recent kibana versions, we come up with a decision of implementing a reusable visualization that covers both cases and potentially can be adopted by other solutions in Kibana. elastic-charts seems a perfect place for it.

Describe the solution you'd like
It would be great to get some assistance with defining a skeleton code so we can develop the actual implementation of the visualization.

Required features:

• hover and click actions on each cell
• rectangular brush tool to select a subset area
• discrete color ranges
• color legend

Additional context
After swim lane visualization is released in elastic-charts it could become a part of the built-in Kibana visualizations included in the Basic distribution, so there is no need to maintain the kibana-swimlane-vis.

Brush control

Brush selection should support the following:

• Highlight selected cells
• Mask labels on the X and Y axis, and the cells itself that outside of the selection area
• Input props should support initial selection
