WHY IT NEEDS A POLICY

Why chart_3d_bar needs a policy

This tool creates new SVG chart graphics but does not execute arbitrary code, delete data, or cause financial transactions. The creation is reversible (charts can be regenerated or deleted). While it modifies the SVG canvas state by adding content, this is a standard Write operation. Severity is low because misuse results only in unwanted chart creation on the canvas with no system-level or destructive impact.

From the tool's definition Tool name 'chart_3d_bar' and description '3D 막대 차트를 생성합니다' (generates a 3D bar chart) indicate creation of SVG graphic content. The verb 'creates' (생성) is characteristic of Write operations.
