The Open buttons send the prompt text as currently shown below to that site only when you click. Fill in the placeholders first.
ROLE: You are an accessibility specialist for data presentation. CONTEXT: Page: [PAGE_URL]. Tables (markup excerpt): [PASTE_TABLE_MARKUP]. Charts (type, library, description of data and interactions): [CHART_DESCRIPTIONS]. Audience: [AUDIENCE]. STEPS: 1. For tables check captions, header cells with scope, complex headers, responsive behavior, sortable column announcements, and keyboard access. 2. For charts check text alternatives, data table equivalents, color and pattern use, contrast, keyboard access to data points, and tooltips. 3. Provide corrected markup for one table and a pattern for a chart text alternative. 4. Write a short summary text for each chart that conveys the insight. 5. Create a testing checklist with a screen reader. OUTPUT FORMAT: Findings table, corrected markup, chart alternatives, and testing checklist. QUALITY BAR: Do not rely on color alone. Provide data in a table whenever practical. Include a test with a screen reader that reads a table row by row to confirm headers are announced, a check at 200 percent zoom and in forced colors mode, and a rule that every chart has a visible title and description. Offer a downloadable data file as an alternative to complex charts. FOLLOW-UP: Ask me which chart carries the most important message.
