Regression prevention and quality gates

Problem

Chart rendering defaults are fragile to code changes — a refactor to axis scaling can silently shift label positions, a color palette update can break contrast ratios, and a new chart type can inadvertently alter shared rendering utilities. Currently, there are no automated gates that catch visual regressions before they reach users. Without visual regression tests (SVG snapshot comparisons), automated accessibility checks, and CI-enforced quality thresholds on the render pipeline, every release carries the risk of degrading chart quality in ways that are invisible until users report them.
