Extension Visuals

Extensions add supporting textual or image information to the application. The following steps demonstrate how to create a simple extension visual with text content and minor HTML formatting.

We are working with dataset Census Data [data source default.census_data].

  1. On the main navigation, click Apps.
  2. Above the left navigation bar, click New Visual.

    The Select a Dataset modal window appears.

  3. In the modal window, find and then click State Census.

    Alternatively, you can use another dataset that uses US Census data.

    An Untitled visual screen appears; it is in the default tabular view.

  4. In the Visuals menu, select extension (row 4, column 6).

    choosing extension chart type

    A new visual screen appears, named Untitled.

  5. In the text box, paste the following code block.

    <h1>2010 United States Census</h1>
    <p>From Wikipedia, the free encyclopedia</p>
    <h2>General information</h2>
    <li>Country: United States</li>

    <p>The 2010 United States Census, known as "Census 2010", is the twenty-third 
    and most recent United States national census. National Census Day, the reference 
    day used for the census, was April 1, 2010. As part of a drive to increase the 
    count's accuracy, 635,000 temporary enumerators were hired. The population of 
    the United States was counted as 308,745,538, a 9.7% increase from the 2000 Census.</p>
  6. Click Refresh Visual.

    Note the text that appears in the lower portion of the screen.

  7. [Optional] You may wish to ensure that the extension appears without a title when it is used in an application. You can then paste the following code at the beginning of the previous code block:

      #viz-title-display {
  8. Click Refresh Visual.

  9. Click Edit next to the title of the visualization.
