Create a clean, minimalist table chart for "Ethical AI Healthcare Solutions", showcasing a 25% diagnostic accuracy gain. The table should have two rows and one column with numeric data: 'Before AI' with '70%' in the first row, and 'After AI' with '87.5%' in the second row. Use a white background with a headerblue border (RGB: 0, 102, 204, 1 pt). Set the first cell of each row ('Before AI', 'After AI') in a headerblue background (RGB: 0, 102, 204) with white text, and the second cell of each row ('70%', '87.5%') in a white background with black text, with the '87.5%' cell highlighted in a light accentgreen fill (RGB: 0, 153, 76). Use Roboto Regular, 12 pt, for all text. Add a subtle yellow arrow (RGB: 255, 204, 0) pointing to the '87.5%' cell for emphasis. Exclude any titles, headings, or extra words beyond the specified labels. Ensure a professional, high-tech aesthetic with flat design, sized at 800x600 pixels, 300 DPI, optimized for website display and print handouts for a healthcare audience
