Remove scatter plots

[F-said]

Problem

In youtube_eda7 there are a couple of scatter plots for time-series data.

These would be better suited as line-plots (which are actually already plotted below).

Expected Output

To prevent confusion, we should remove the mentioned scatter plots for time series data and instead keep the line plots.

Definition of done

Scatter plot time-series removed, line-plots added where necessary, committed, pushed, and merged.
