Use this skill when:
This skill outputs a PENCIL_PLAN. The Agent then calls Pencil MCP tools in order: open_document, set_variables, batch_design, optionally get_screenshot.
Use mcp__pencil__set_variables to register ECharts-related design tokens (chart theme colors, font). Follow .pen file schema.

Use mcp__pencil__batch_design to create a "Charts Overview" frame with placeholder sections for chart types (data-viz components):
Organize frames using Auto Layout. Keep each batch_design call to maximum 25 operations.
