Type that can be used for creating frames using the C# collection initializer syntax. You can use `new FrameBuilder.Columns<...>` to create a new frame from columns or you can use `new FrameBuilder.Rows<...>` to create a new frame from rows. ## Example The following creates a new frame with columns `Foo` and `Bar`: var sampleFrame = new FrameBuilder.Columns<int, string> { { "Foo", new SeriesBuilder<int> { {1,11.1}, {2,22.4} }.Series } { "Bar", new SeriesBuilder<int> { {1,42.42} }.Series } }.Frame; [category:Frame and series operations]
