At 2:21, Andrew says " Because there are only two possible outputs or two possible categories in this example, you can also plot this data set on a line like this." I think that we can plot the data on a line not because there are only two outputs, but because there is only one feature.
Hey @Vivek_Chandel,
Welcome to the community. You are absolutely correct in your thinking. Even if there are more than 2 classes, we can still plot the data on a single line using as many different symbols as the number of classes. I will make sure to report this to the team. Thanks for your feedback.
Cheers,
