Data-Driven Architecture
All calculators draw from centralized JSON data files in data/healthcare/:
- reference-ranges.json — Lab test reference ranges, cardiovascular norms and interpretation guidelines
- bmi-ranges.json — WHO BMI categories, pediatric percentiles, ideal weight formulas and body composition ranges
- medical-units.json — Unit conversion factors for weight, height, glucose and temperature
- currency-data.json — Multi-currency support (INR, USD, EUR, GBP, AED, CAD, AUD, JPY, SGD) with live-fresh exchange rates
- risk-factors.json — ASCVD risk groups, Framingham risk factors and diabetes risk scoring
- recommendations.json — Smart recommendation engine: triggers map health metrics to related calculators
Smart Recommendation Engine
When you calculate your BMI, blood pressure, cholesterol or blood sugar, the engine evaluates your results against medical thresholds and automatically recommends related calculators. For example, a high BMI result suggests the Calories Burn Calculator, Ideal Weight Calculator, Body Fat Calculator and Water Intake Calculator.

- Canvas charts — drawBarChart, drawDonut, drawGauge, drawProgressCircle, drawRiskMeter, drawTimeline, drawGrowthChart
- Multi-currency formatting — fmtINR, fmtUSD, fmtCurrency with locale-aware formatting
- Reports — buildReportTable, downloadReport (CSV), downloadPDFReport (print-ready PDF)
