      description: 'Creates a new experiment view override configuration for a dataset with column display settings.

        This endpoint allows you to customize how experiment results are displayed by configuring

        column-specific overrides including colors, precision, and visibility.


        The request must include a ''column_overrides'' array with at least one override configuration.

        Each column override can specify:

        - column: Required field name (must start with inputs, outputs, reference_outputs, feedback, metrics, attachments, or metadata)

        - color_gradient: Optional array of [number, color] tuples for numeric data visualization

        - precision: Optional number (1-6) for decimal places in numeric columns

        - hide: Optional boolean to control column visibility


        Example request body:

        {

        "column_overrides": [

        {

        "column": "outputs.accuracy",

        "color_gradient": [[0.0, "#ff0000"], [0.5, "#ffff00"], [1.0, "#00ff00"]],

        "column": "inputs.model_type",

        "hide": false
