/**
 * The base class for report visualizations that output HTML and use JavaScript.
 *
 * 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),
 * - a button that allows users to switch visualizations,
 * - a control that allows users to export report data in different formats,
 * - a limit control that allows users to change the amount of rows displayed (if
 *   {@link Piwik\ViewDataTable\Config::$show_limit_control} is true),
 * - and more depending on the visualization.
 *
 * ### Rendering Process
 *
 * The following process is used to render reports:
 *
 * - The report is loaded through Piwik's Reporting API.
 * - The display and request properties that require report data in order to determine a default
 *   value are defaulted. These properties are:
 *
 *   - {@link Piwik\ViewDataTable\Config::$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
 *                                                        filters are called, but before other filters. This
 *                                                        method should be used if you need the report's
 *                                                        entire dataset.
 * - **afterGenericFiltersAreAppliedToLoadedDataTable**: Called after generic filters are applied, but before
 *                                                       queued filters are applied.
 * - **afterAllFiltersAreApplied**: Called after data is loaded and all filters are applied.
 * - **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.
 *
 * To learn more read the [Visualizing Report Data](/guides/visualizing-report-data#creating-new-visualizations)
 * guide.
 *
 * ### Examples
 *
 * **Changing the data that is loaded**
 *
 *     class MyVisualization extends Visualization
 *     {
 *         // load the previous period's data as well as the requested data. this will change
 *         // $this->dataTable from a DataTable instance to a DataTable\Map instance.
 *         public function beforeLoadDataTable()
 *         {
 *             $date = Common::getRequestVar('date');
 *             list($previousDate, $ignore) = Range::getLastDate($date, $period);
 *
 *             $this->requestConfig->request_parameters_to_modify['date'] = $previousDate . ',' . $date;
 *         }
 *
 *         // since we load the previous period's data too, we need to override the logic to
 *         // check if there is data or not.
 *         public function isThereDataToDisplay()
 *         {
 *             $tables = $this->dataTable->getDataTables()
 *             $requestedDataTable = end($tables);
 *
 *             return $requestedDataTable->getRowsCount() != 0;
 *         }
 *     }
 *
 * **Force properties to be set to certain values**
 *
 *     class MyVisualization extends Visualization
 *     {
 *         // ensure that some properties are set to certain values before rendering.
 *         // this will overwrite any changes made by plugins that use this visualization.
 *         public function beforeRender()
 *         {
 *             $this->config->max_graph_elements = false;
 *             $this->config->datatable_js_type  = 'MyVisualization';
