It depends on whether what you want is actually improved antialiasing, or if what you really want is a smoother curve interpolated through the data points.
If you want better antialiasing, you'd have to look at the SVG options - though I don't see much room for improvement in this case, honestly.
If you want a smooth curve then what you want is the spline chart type:
Just keep in mind that a spline distorts the data by using a particular formula to smooth a curve between points, which can increase the severity of the difference between high and low points - it shouldn't be used simply for aesthetics.
