  * Report visualizations that extend from this class will be displayed like all others in
  * the Piwik UI. The following extra UI controls will be displayed around the visualization
  * itself:
- * 
+ *
  * - report documentation,
  * - a footer message (if {@link Piwik\ViewDataTable\Config::$show_footer_message} is set),
  * - a list of links to related reports (if {@link Piwik\ViewDataTable\Config::$related_reports} is set),

  * - and more depending on the visualization.
- * 
+ *
  * ### Rendering Process
- * 
+ *
  * The following process is used to render reports:
- * 
+ *
  * - The report is loaded through Piwik's Reporting API.
  * - The display and request properties that require report data in order to determine a default
  *   value are defaulted. These properties are:
- * 
+ *
  *   - {@link Piwik\ViewDataTable\Config::$columns_to_display}
  *   - {@link Piwik\ViewDataTable\RequestConfig::$filter_sort_column}
  *   - {@link Piwik\ViewDataTable\RequestConfig::$filter_sort_order}
- * 
+ *
  * - Priority filters are applied to the report (see {@link Piwik\ViewDataTable\Config::$filters}).
  * - The filters that are applied to every report in the Reporting API (called **generic filters**)
  *   are applied. (see {@link Piwik\API\Request})
  * - The report's queued filters are applied.
  * - A {@link Piwik\View} instance is created and rendered.
- * 
+ *
  * ### Rendering Hooks
- * 
+ *
  * The Visualization class defines several overridable methods that are called at specific
  * points during the rendering process. Derived classes can override these methods change
  * the data that is displayed or set custom properties.
- * 
+ *
  * The overridable methods (called **rendering hooks**) are as follows:
- * 
+ *
  * - **beforeLoadDataTable**: Called at the start of the rendering process before any data
  *                            is loaded.
  * - **beforeGenericFiltersAreAppliedToLoadedDataTable**: Called after data is loaded and after priority
@@ -76,20 +76,20 @@ use Piwik\ViewDataTable\Manager as ViewDataTableManager;
  * - **beforeRender**: Called immediately before a {@link Piwik\View} is created and rendered.
  * - **isThereDataToDisplay**: Called after a {@link Piwik\View} is created to determine if the report has
  *                             data or not. If not, a message is displayed to the user.
- * 
+ *
  * ### The DataTable JavaScript class
- * 
+ *
  * In the UI, visualization behavior is provided by logic in the **DataTable** JavaScript class.
  * When creating new visualizations, the **DataTable** JavaScript class (or one of its existing
  * descendants) should be extended.
