Parameters from the server's own tool schema.
This tool creates/generates a chart from provided data. It is a write/creation operation producing a chart artifact. It has low blast radius as it only generates a visualization and does not affect financial, destructive, or execution-level operations. Confidence is moderate because the description is brief and doesn't clarify where/how the chart is stored or rendered.
