Please let me know, how to create a half circle donut chart in Tableau. Please see the attached image. Lables can be fine with inside donut/outside of donut.

Thanks in advance.

This is possible, but not really easy. At least, not a beginner task. People do it. You'd probably use a polygon mark type and have to do some trig calcs and data padding. A full circle donut chart is very simple by comparison. - Alex Blakemore
Alex, Please let me know if you find a solution for it. - Narasimha L
I recommend finding a simpler design if you are new to Tableau. But if you are set on a half donut, you'll need to learn some of the trickier parts of Tableau and put in some work. That effort may pay off long term. A good place to start is youtu.be/myyakEnuqa8 and then learn table calcs and data densification. Or you can make a full donut and hide the bottom as @unni_ukmv suggests. If you are in hurry, I'd try that first - Alex Blakemore
Thanks Alex, It helps me in short term way, whereas, we need to figure it out for a permanent solution as you suggested in your above comment like using trig calcs & data padding. Hope it would be best solution for us. Thanks.! - Narasimha L
Alex, I really thanks to you for sharing the wonderful knowledge "A good place to start is youtu.be/myyakEnuqa8 and then learn table calcs and data densification. " I was really scared about these trig cals & x,y calcs, now I can learn and explore more related data densification charts. Hope, D3js.org is the best site for learn many charts to densification charts. Thanks.! - Narasimha L

There is an easy method to do this. Basically it is a tweek in full donut chart. We will create a full donut chart and hiding the bottom half.
