/**
* This is the global function which encapsulates all variables and methods. All
* parameters are optional.
*
* The shortest possible way to get up and running a graph with the shipped sample data:
*
* example = netGobrechtsD3Force().render();
*
* You can then interact with the graph API like so:
*
* example.width(800);
* @see {@link module:API.start}
* @see {@link module:API.render}
* @see {@link module:API.resume}
* @param {string} [domContainerId] - The DOM container, where the graph should be rendered
* @param {Object} [options] - The configuration object to configure the graph
* @param {string} [apexPluginId] - APEX plugin only: The plugin identifier for the AJAX calls
* @param {string} [apexPageItemsToSubmit] - APEX plugin only: Page items to submit before an AJAX call
* @returns {Object} The public graph API function to allow method chaining

* PUBLIC GRAPH FUNCTION AND API METHODS

/**
* This method starts the graph. You can configure your graph with all the available methods, but without the `start` method your changes will NOT take into effect.
*
* You can pass new data (see {@tutorial included-sample-data}) to the `start` method. Data can be a XML string, JSON string or JavaScript object (JSON). If you use the APEX plugin, then the `start` method internally does the AJAX call to your Oracle database, but you can prevent this behavior by passing data to this method.
*
* This also means, that you can use data from a textarea or a report for the APEX plugin, to overwrite the existing data and you do not need to configure any query to run this plugin. If you do so and you do not pass data to the `start` method on the very first call, then the plugin provides sample data - it is the same data with the [APEX online demo](https://apex.oracle.com/pls/apex/f?p=18290:1) of this plugin, there is no query configured and you get therefore the sampledata :-)
* @see {@link module:API.render}
* @see {@link module:API.resume}
* @param {(string|Object)} [data=Sample data EMP table flavoured] - Can be a XML string, JSON string or JavaScript object (JSON)
* @returns {Object} The graph object for method chaining.

If the calculated scale factor is less or greater then the configured minimum and maximum scale factors, then these configured scale factors are used.
