💡 Background and solution

Problems:

Problem Type	Manifestation in Codebase	Impact
Complexity	Large, monolithic functions; deep nesting; implicit data flow	Hard to read, debug, or extend
Coupling	Tight integration of logic and utilities	Difficult to refactor or reuse
Testability	No colocated tests; hard to isolate units; no DI	Hard to write meaningful unit tests
Modularity	Chart-specific logic inline, not modular	Low reusability, high duplication risk

Refactor Plan:

• [ ] Decompose Monolithic Functions Break down large functions (e.g., scorer, baseBarScore) into smaller, single-responsibility functions. Extract chart-type-specific logic into separate modules/files.
• [ ] Modularize Rule and Scoring Logic Move rule definitions and configurations out of inline objects into dedicated, reusable modules. Create a registry or factory for chart scoring strategies.
• [ ] Improve Data Flow and Parameter Handling Replace large, loosely-typed parameter objects with well-defined interfaces. Pass only necessary data to each function to reduce implicit dependencies.
• [ ] Introduce Dependency Injection Inject utility functions and configuration instead of importing them directly. Allow for easy mocking/stubbing in tests.
• [ ] Increase Testability Expose internal logic and utility functions for direct testing. Write unit tests for each isolated function and rule. Add integration tests for high-level scoring flows.
• [ ] Enhance Documentation and Typing Add clear JSDoc/type annotations for all public and internal APIs. Document the expected input/output for each function.
