It is sent back to the AI Agent.\n- The AI Agent uses this image in its response.\n- For example, you can ask the AI Agent to generate a chart about the top 5 movies at the box office\n\n\n**Notes**\n- The full Quickchart.io specifications have not been integrated, thus there are some possible glitches (e.g due to the size of the graph, radar graphs are not displayed properly)\n- This could be provided to any automation, not only AI Agents."
