## Why generate_funnel_chart is rated Medium

This tool generates visualizations (charts) in an offline manner using ECharts SVG SSR. It creates new data artifacts (chart images) but does not modify existing persistent data, delete data, execute arbitrary code, or move money. The output is a rendered visualization that does not alter system state beyond creating a temporary chart artifact.

From the tool's own definition: "Tool name 'generate_funnel_chart' and description 'Generate a funnel chart to visualize progressive reduction across stages' indicate chart/data generation without data persistence or external side effects."

## Use case

AI agents use generate_funnel_chart to create or update resources in Kylin Offline MCP ECharts, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Kylin Offline MCP ECharts environment.
