How to Plot K

3. Plotting Label 0 K-Means Clusters . Now, it's time to understand and see how can we plot individual clusters. The array of labels preserves the index or sequence of the data points, so we can utilize this characteristic to filter data points using Boolean indexing with numpy. Let's visualize cluster with label 0 using the matplotlib library.

Compute k-means clustering. Parameters X {array-like, sparse matrix} of shape (n_samples, n_features) Training instances to cluster. It must be noted that the data will be converted to C ordering, which will cause a memory copy if the given data is not C-contiguous. If a sparse matrix is passed, a copy will be made if it's not in CSR format.
