## Example call (MCP tools/call, JSON-RPC 2.0)

```json
{
  "jsonrpc": "2.0",

  "params": {
    "name": "generate_tree_chart",
    "arguments": {}

## Why generate_tree_chart is rated Medium

The tool generates and outputs a chart visualization, which constitutes creating data (the rendered SVG). It does not execute arbitrary code, delete data, move money, or query external systems. It is reversible (chart can be regenerated or discarded). This is categorized as Write rather than Read because it actively produces a new artifact rather than merely retrieving existing data.

From the tool's own definition: "Tool name 'generate_tree_chart' and description 'Generate a tree chart to display hierarchical data structures' indicate the tool creates/outputs a visual artifact (chart)."

## Use case

AI agents use generate_tree_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.
