Check my chart for accessibility problems

Checks a described chart for accessibility problems with color, contrast, text and alternatives, and lists the fixes in order of effort.

Task: Check the chart described below for accessibility problems and list the fixes from easiest to hardest. Context: The chart is published in [web page, PDF, slide or report] for [audience]. Known needs among readers are [color-blindness, low vision, screen readers or none known]. The chart is made in [tool]. Rules: - Check color use, contrast between marks and background, text size, reliance on color alone, labels, and a text alternative for screen readers. - Quote the part of my description each problem refers to, and say when my description is too thin to judge a point instead of assuming. - Give the fixes in order of effort, each as one action, and add a draft text alternative of at most 40 words based only on what I described. - Do not state exact legal or standard requirements as fact. Tell me to check the current rules that apply to my organization. Result: A table with the columns problem, why it matters and fix, ordered by effort, then the draft text alternative. Material: [describe the chart: type, colors, text sizes, labels, legend and what it shows]
