World's Longest Rivers Infographic with National Flag Details

Geography infographic titled "World's Longest Rivers". Reframe the requested country profile card into a geography atlas-style comparative poster about the longest rivers of the world, using a sketchnote, high-contrast modern palette. Dominant visual: a ranked vertical bar chart combined with simplified world map highlights showing the course and continent of each major river. Include visually prominent small accurate national flags of countries associated with each river’s basin or mouth, with correct colors and proportions, to satisfy the flag-related visual intent, but keep the focus on rivers rather than countries. Show top rivers such as Nile, Amazon, Yangtze, Mississippi–Missouri, Yenisei, Yellow River, Ob–Irtysh, Paraná, Congo, Amur, Lena, Mekong, Mackenzie, Niger, and Murray–Darling. For each river, include concise English labels for length, continent, source, mouth, and countries crossed. Add a small legend and comparison scale in kilometers. Use clean hand-drawn sketchnote accents, arrows, icons, and callout boxes. If any borders appear on the map, render disputed borders neutrally with gray dashed lines and no political framing, no territorial claims, no political bias on disputed borders.
