request feature to show diskIO graph just similar to bootchart #674

In bootchart graph, we can see diskIO graph like below: image

I would expect perfetto provide similar feature.

If any sql command can do the same, please help share how we can do it.

We have tried to add I/O chart by custom data source. But the result is not good engoth cause the sample rate can't be stable...

We don't have any built-in support for Disk IO because it's never been a focus for us.

Patches for adding support for this are welcome but we don't have any plans to add something ourselves.
