Hi Michael,
You can build this using a dual-axis pie chart approach in Tableau.
Create calculated fields for each range (Red, Orange, Green) and use them to build the background segments, then overlay another pie or shape mark for the indicator/needle.
For your ranges:
* 0–70% = Red
* 71–94% = Orange
* 95–100% = Green
A lot of people use calculated angles + dual axis to create the speedometer effect.
This tutorial may also help: the Flerlage Twins gauge chart examples are very good.
