[charts] Add batch bar plot
Fix naming collision Fix border radius Handle border radii greater than width/height Add example and renderer prop Remove unused code WIP: Use flatbush for finding the clicked bar Add simple animation Split Render series separately Implement highlight and fading Import fixing. Remove unused prop. Update docs Slight performance improvements Share appendAtKey Fix layout-dependent animation Return layout and origin in bar plot data Fix rebase Remove unused prop Fix imports Abstract position in getClosestPoint Fix type issues Handle both layouts when creating bar flatbush Fix flatbush with nulls Fix renderer prop not being forwarded Fix animation Remove disableHover mention Try to implement onItemClick Investigate flatbush issue Remove flatbush usage Add on item click Update docs. Cleanup batch bar after on item click working. Some more progress Remove memo for now Add fading and highlighting (missing animation) Remove animation from highlight/fade Fix type imports Fix pointer leave Rename Add brightness filter to highlighted item Revert demos Fix types Fix rebase Address feedback Use ordinal time ticks Gen stuff [charts] Add batch bar plot Fix naming collision Fix border radius Handle border radii greater than width/height Add example and renderer prop Remove unused code WIP: Use flatbush for finding the clicked bar Add simple animation Split Render series separately Implement highlight and fading Import fixing.
