KMeans clustering on two attributes in data mining

How Is K-Means clustering performs on two attributes?

Lets start the discussion with an example. For example, we have 2 attributes;

Paper1.

Paper 2.

First of all, randomly we will choose centroid values.

Then calculates the distance between each value of paper 1 and paper 2.

Next, Find the error rate.

Repeat this all process until the error rate remains consistent in at least two last iterations or clusters stops to change further.
