Chart Master — Financial Visualization AgentFinance Skill

A financial visualization skill that produces clean, publication-quality charts optimized for markdown reports. Platform detection table routes output format: Claude Code/Claude.ai → Mermaid + HTML/Chart.js (fallback ASCII), Gemini/Cursor/Copilot → Mermaid (fallback ASCII), plain markdown/terminal → ASCII (fallback text table), HTML export → HTML/Chart.js (fallback Mermaid). Default rule: "Always produce Mermaid first. If the user requests rich, interactive, or HTML report, also produce the HTML/Chart.js version. If Mermaid won't render, fall back to ASCII." 12 chart types with full code templates: (1) Price with Moving Averages — MA line chart with MA20/MA50/MA200 overlays, Golden Cross (▲) and Death Cross (▼) annotations, red tint below MA200; (2) Price + Volume — dual-panel chart with green/red volume bars matching up/down days, dual y-axes; (3) Return Distribution — histogram with green/red bins, mean/std dev/skew/VaR(95%)/CVaR(95%) stats; (4) RSI Indicator — momentum panel with overbought 70 and oversold 30 reference lines; (5) MACD — trend & momentum panel with MACD line, signal line, histogram, bullish/bearish cross annotations; (6) Revenue/Earnings Growth — bar + line combo (Mermaid xychart-beta); (7) Valuation Comparison — horizontal bar (P/E, EV/EBITDA, P/S vs. peers); (8) Margin Trends — multi-line (gross/operating/net margin); (9) Portfolio Allocation — pie chart (sector weights, asset allocation); (10) Price vs. Fair Value — range/gauge chart (bear case, fair value, bull case, current price position, UNDERVALUED/FAIRLY VALUED/OVERVALUED zones); (11) Signal Dashboard — multi-metric scorecard (fundamental/technical/valuation/sentiment/macro scores 0-10 with color-coded bars and composite); (12) Support & Resistance — price level map (strong resistance, recent high, MA50 support, MA200 major support, bear-case support, risk/reward ratio). HTML/Chart.js style guidelines: consistent color palette (price blue, MA50 amber, MA200 red, bullish green, bearish red, RSI purple), standard chart options (Inter font, responsive, grid styling). 6-step workflow: identify data → select chart type → render (HTML/Chart.js for rich, Mermaid for markdown, ASCII universal) → label all axes with units → annotate key events → summarize in 1-2 sentences. Data verification before analysis: fetch current price/52-week range/market cap, state source, flag stale data. Investment Signal box with score guide and thesis invalidation checklist. "Educational analysis only. Not financial advice." Pure prompt skill — no runtime, no dependencies, no API keys. Works on all AI platforms.
