Fix Davis Bouldin Index Formula

[ParagEkbote]

Fixes #180

As described in the issue, I've kept the same colors (purple and cyan) for the text and arrows. Please let me know if any further corrections are needed and I will make the necessary changes.

Hi @ParagEkbote,

Sorry, but this wasn’t exactly what I had in mind. I think I did a poor job explaining the issue.

As you know, the current formula only colors the $i$ and $j$, but that’s not what we want. What I would prefer instead is to color and add arrows to the following parameters:

$k$: total number of clusters
$R_{ij}$: similarity between clusters $i$ and $j$
$s_i$: within-cluster scatter
$d_{ij}$: distance between the centroids

This means we would need to use four different colors and rows with their respective descriptions.

No worries! I'll modify the colors as required.Could you please let me know what 4 colors you'd prefer to use for the given parameters?
