Datapoints on the plot are drawn at uniform interval from parametric equations x(t) = t and y(t) = sin(2t), where t ranges from −7 to 7. The blue bidirectional line represents the first Principal Component, which explains 98% of the variance in the data. The red bidirectional line represents the second Principal Component, which explains the rest of the variance in the data.
