Add logarithmic scale to Gauge

### Description

In the industrial automation field a Gauge is a nice way to show sensor data.
Thanks alreasy for the intial version.

It would be good to have a option to change from linear scale in the gauge to **log**scale.

See Example https://e-tinkers.github.io/d3-dashboard-gauge/

For the start i think in the industrial sector a log10 would be fine.

There is a nice implementation under the MIT-licence
