WHY IT NEEDS A POLICY

Why create-chart-using-googlecharts needs a policy

This tool creates data artifacts (chart images) and can write them to the filesystem. However, the write operation is reversible (files can be deleted), the scope is limited to visualization outputs, and there is no destructive, financial, or code execution capability. The low severity reflects that misuse would result in harmless file creation rather than data corruption or unauthorized system access.

From the tool's definition Tool description states 'save chart image to file', which creates/modifies data. The tool generates chart visualizations and optionally persists them as files.
