Visual Encoding & Comparative Anatomy

A waterfall chart (also known as a bridge chart) explains how an initial starting value increases or decreases through a series of sequential positive and negative increments, resulting in a final total. It plots these intermediate changes as floating bars, connected by reference lines to show the cumulative effect of each step. All data is processed entirely locally on your machine, guaranteeing your financial data remains private with no server uploads.
