 *
 * @return array
 *   An associative array containing:
 *   - name: (string) A human-readable name for the analysis plugin.
 *   - description: (string) A brief description of what the analysis does.
 *   - data: (array) An array containing up to three analysis data points to be
 *     displayed in the Analyze tab. Each data point should be an associative
 *     array with the following keys:
 *     - label: (string) The label for the data point.
 *     - value: (mixed) The value of the data point, which could be a score,
 *       message, or other metrics.
 *     - component: (string) The component type used to render this data point
 *       (e.g., 'linear_gauge', 'table').
 *     - settings: (array) An optional array of additional settings specific to
 *       the component type.
 *       For a linear gauge, the settings might include:
 *       - caption: (string) The caption for the gauge, typically the data point
 *         label.
 *       - range_min_label: (string) The label for the minimum value range.
 *       - range_mid_label: (string) The label for the mid value range.
 *       - range_max_label: (string) The label for the maximum value range.
 *       - range_min: (string) The minimum value of the gauge.
 *       - range_max: (string) The maximum value of the gauge.
 *       - value: (float) The value to be represented on the gauge (as a
 *         percentage).
 *       - display_value: (string) The value to display in the gauge.
 *   - report_link: (optional) An associative array for the full report link,
 *     with the following keys:
 *     - title: (string) The title for the link.
 *     - callback: (callable) A function that returns the full report data to
 *       be displayed in a second-level tab.
