## Summary This PR adjusts the prompt generation logic for visualization configuration in the `create_visualization` tool. - removes indentation from the included schema. - removes the duplicated `existingConfig` schema By removing the indentation, I was able to reduce the number of tokens required to create a visualization config by about half (for XY charts). _I don't think_ omitting the formatting would impact the visualization configs generated by an LLM.
