This example demonstrates aspect ratio banking, a technique that adjusts the width-to-height ratio of a chart to make line slopes average around 45 degrees for optimal visual perception. The code implements an `AspectRatioBanker` function that computes this ratio using either the average absolute angle or median absolute slope methods, then applies Newton-Raphson iteration to solve for the optimal value. It uses Underscore.js utilities for data operations and accepts custom x and y scales, with an `adjustToAxes` method that currently lacks a functional implementation for final axis adjustment. The visualization shows how different banking algorithms calculate and refine aspect ratios for line chart data.
