Initialize uCharts. design system components chart placeholders and data-viz tokens in Pencil.
Initialize uCharts. design system components chart placeholders and data-viz tokens in Pencil.
Constraint: Only use this skill when the user explicitly mentions "Pencil" and "uCharts" (or "qiun-data-charts") or when orchestrating a Pencil design system initialization task for charts.
Use this skill when you need to initialize a chart/design system based on uCharts specifications in a .pen file: set up chart theme colors and create placeholder frames for chart types (line, bar, pie, etc.).
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 uCharts-related design tokens (chart theme colors, font). Follow .pen file schema.
Chart colors (series)
ucharts-color-1: #1890ffucharts-color-2: #52c41aucharts-color-3: #faad14ucharts-color-4: #f5222ducharts-color-5: #722ed1Axis / grid
ucharts-axis-color: #e8e8e8ucharts-text-color: #666666ucharts-font-size: 12pxFill from uCharts theme docs if more tokens are needed.
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.
