    This is the code that draws the viz based on the current encodings and data. This example is extremely simplified and just uses the method called to retrieve the encoding, `worksheet.getVisualSpecificationAsync()`. From the `visualSpec`, the list of encodings is collected from the Marks card. The HelloVizExtensions example just has one encoding tile labeled "Drop..." The list of fields that are dropped on the tile are displayed in the content area of the worksheet. In real life, you would use multiple encodings that would correspond to the coordinates in your visualization (for example, x, y, and r). 
 
-   The other missing piece from this code example is the data. To retrieve the data from the worksheet, you call the `worksheet.getSummaryDataReaderAsync()` method. This method returns a `DataTableReader`, which you use to page through the summary data in the worksheet, to extract the rows of data. See the conncecteScatterplot viz extension sample to see an example of how this is done.

   Finally, after you have the data and the map of encodings to fields you can pass this to code that can generate a scatterplot, a Sankey diagram, or network visualization. This example just prints the fields to the content area of the worksheet. But it's a start.

-Each extension must be uniquely identified. If multiple extensions in a workbook share the same combination of URL, ID, and version number, the extension zones will not load properly. As a best practice, use unique identifiers for each viz or dashboard extension when creating the manifest file (.trex). For example, for viz extensions, make sure that the same `<worksheet-extension>` `id` and `extension-version`, and the `<source-location>` `url` aren't all used in other extensions.
