Is there a way to create a pie chart in NS?

Use Google Charts

That requires scripting, right?

Yes

Thanks, @Eric B. Are you aware of any other alternative that does not require scripting?

I'm not aware of any other alternative that uses Google Charts that won't require scripting in Netsuite.

Thanks again, @Eric B

I think only in reports. At the bottom of the report choose graph and it does pie charts.
