ASP.NET MVC Chart Setting a theme

The theme for the chart can be set through the Theme property, which accepts a string as its argument.
The value can be the name of a valid theme, such as “Light” or “Dark” in the present version of the chart, or the name of a custom one.
This is demonstrated in the code snippet below:

(Html.ShieldChart()
    .Name("chart")
    .Theme("Dark")
