	<p class="text-left"> Visualization is inspired by
	<a href="http://mbostock.github.io/d3/talk/20111018/partition.html">the implementation</a> of partition layout.</p>

	<p class="text-left">You can visualize hypothetical data containing sales orders for clothes products. Summarizing aggregation is performed on the number of ordered units for the hierarchy of three dimensions:
	</p>
	<ul class="custom-bullet">
	<li>the sales person placing an order,</li>
	<li>the name of the ordered product,</li>
	<li>the state of an order (open, closed, archived).</li>
	</ul>

	<p class="text-left">You can change the hierarchy of dimensions at any time which will trigger visual transition to new data view. Click any field on the chart to ascend and descend.
	</p>

	<p class="text-left"><a href="product_orders.json">Data source</a> is in flat structure that can be easily retrieved with the likes of 'group by' statement.</p>
	</div>

	<div class="row">
	<div class="col-sm-12">
	<p class="text-left">If time allows I will
	migrate it from Bootstrap modal to more generic HTML. In the meantime, if you would like to use it, you need to add
	core chart HTML content to your DOM, invoke <code>openVisualizationModal(dimensionsTable, dataSourceURLFn, chartTitle)</code> function and prepare the data in <a href="product_orders.json">such</a> flat structure.
