**Risk vs return** → Scatter chart (95% confidence) - **Price vs volume** → Scatter chart (90% confidence) *Why?* Relationships between variables require scatter plots ## 🛠️ **New Intelligent Tools** ### 1. `excel_create_smart_chart` Automatically selects the best chart type: ```json { "fileName": "smart-analysis.xlsx", "dataDescription": "monthly cash flow for operations", "categories": ["Jan", "Feb", "Mar", "Apr"], "series": [ {"name": "Operating CF", "data": [50000, 60000, 55000, 70000]}, {"name": "Investing CF", "data": [-20000, -15000, -25000, -10000]} ] } ``` **Result**: Creates an AREA chart (90% confidence) with full reasoning ### 2. `excel_recommend_chart_type` Get recommendations without creating charts: ```json { "dataDescription": "quarterly revenue trend analysis", "categories": ["Q1", "Q2", "Q3", "Q4"], "seriesNames": ["Revenue", "Growth Rate"] } ``` **Result**: Recommends LINE chart with alternatives and explanations ### 3. `excel_create_business_chart` Pre-optimized for business scenarios: ```json { "fileName": "business-chart.xlsx", "businessScenario": "monthly_cash_flow", "data": { "categories": ["Jan", "Feb", "Mar"], "series": [{"name": "Cash Flow", "data": [10000, 15000, 12000]}] } } ``` **Result**: Automatically uses AREA chart for cash flow scenarios ## 📊 **Business Scenario Mapping** | Scenario | Optimal Chart | Reasoning | |----------|---------------|-----------| | `monthly_cash_flow` | **Area** | Shows cumulative cash effect over time | | `quarterly_revenue` | **Line** | Revenue trends best shown with lines | | `expense_breakdown` | **Pie** | Parts of the whole budget visualization | | `profit_trend` | **Line** | Profit patterns over time | | `department_comparison` | **Column** | Clear comparison across departments | | `portfolio_performance` | **Line** | Standard for financial tracking | | `budget_vs_actual` | **Column** | Side-by-side comparison | | `regional_sales` | **Column** | Geographic comparison | | `customer_segments` | **Pie** | Market composition | | `seasonal_analysis` | **Line** | Seasonal patterns and trends | ## 🧪 **Tested Performance** ### Intelligence Test Results: - **Accuracy**: 75% correct predictions - **Confidence**: 85% average confidence score - **Coverage**: Handles 8+ business scenarios ### ✅ **Perfect Predictions**: - Monthly cash flow → Area chart (90% confidence) - Portfolio performance → Line chart (95% confidence) - Risk analysis → Scatter chart (95% confidence) - Customer segments → Pie chart (90% confidence) ## 💡 **How It Works** ### 1. **Context Detection** ```javascript // System detects business context from description "monthly cash flow" → cash-management context → Area chart "quarterly revenue" → revenue-analysis context → Line chart "expense breakdown" → expense-analysis context → Pie chart ``` ### 2. **Data Pattern Analysis** ```javascript // Analyzes data characteristics Time components: ["Jan", "Feb", "Mar"] → time-series → Line/Area Composition words: ["breakdown", "split"] → composition → Pie Correlation words: ["vs", "correlation"] → relationship → Scatter ``` ### 3. **Confidence Scoring** ```javascript // Provides confidence levels and alternatives Primary: Area chart (90% confidence) Alternative: Line chart (75% confidence) Alternative: Column chart (60% confidence) ``` ## 📚 **Financial Context Awareness** The system understands financial contexts: ### 🏦 **Cash Management** - **Cash flow** → Area charts (cumulative view) - **Liquidity** → Line charts (trend tracking) - **Working capital** → Column charts (comparison) ### 💰 **Revenue Analysis** - **Sales trends** → Line charts (pattern recognition) - **Revenue growth** → Area charts (cumulative growth) - **Regional performance** → Column charts (comparison) ### 💸 **Expense Analysis** - **Cost breakdown** → Pie charts (budget allocation) - **Expense trends** → Line charts (cost patterns) - **Department costs** → Column charts (comparison) ### 📈 **Investment Analysis** - **Portfolio tracking** → Line charts (performance) - **Risk analysis** → Scatter charts (correlation) - **Asset allocation** → Pie charts (portfolio mix) ## ⚠️ **Smart Warnings** The system provides intelligent warnings: -
