Answer
Infographics default to a portrait layout. State landscape, square or an aspect ratio if you prefer one, or ask to preserve a reference image’s dimensions. Those explicit directions take priority.
An infographic with small charts is still a complete image request. Its embedded charts do not turn it into a standalone data-chart request. Use Text and a chart request when you need native chart data, an exact table or a CSV export.
Image requests can create infographics and custom memes using automatic model selection and the normal successful-image price. Choose Image explicitly when you want custom artwork.
