Generate and visualize contour plots for hyperparameter optimization results. Customize parameters, target values, and labels to analyze objective functions effectively on the Optuna MCP Server.

Instructions

Return the contour plot as an image.

    Args:
        params:
            Parameter list to visualize. The default is all parameters.
        target:
            An index to specify the value to display. To plot nth objective value, set this to n.
            Note that this is 0-indexed, i.e., to plot the first objective value, set this to 0.
        target_name:
            Target’s name to display on the color bar.
