[I] Pie Chart crashes when Name Column is empty [texera]
carloea2 opened a new issue, #8167:
URL: https://github.com/apache/texera/issues/8167
### What happened?
The Pie Chart descriptor validates its Value Column but does not validate its required Name Column. An empty Name Column passes workflow code generation and becomes an empty pandas column name at execution time.
Before: an empty Name Column reaches pandas and fails with a KeyError.
After: the descriptor rejects the configuration with `Name Column cannot be empty` before Python execution.
### How to reproduce?
1. Create a Pie Chart operator.
2. Set Value Column to a numeric column such as `amount`.
3. Leave Name Column empty.
4. Generate or run the operator code.
5. Observe that the generated `dropna` call looks up an empty column name and fails.
### Version or branch
1.3.0-incubating-SNAPSHOT on main
### Commit hash
70c21145887920528d7d5540e3fb790b43e8b759
### Relevant log output
pandas raises a KeyError for the empty column name.
