In the given Plunk example, Google "pie" chart is working
BUT "table" chart is not working(meaning, "table" chart is in the DOM but it is not visible AND also makes 'pie' to disappear).
Both examples are taken from the demo docs where both are working i.e. both are visible.
Why 'table' chart is not visible in the Plunk example?
