I was viewing a video about the declination in fertility rates when I saw a good line chart. This is a multiple graphs line and each line have different form this can be useful for readers don't get confused comparing the lines because the colors is not enough for classify when you have various line.
This method could be useful when we have a up to +20 lines for plotting.
You don't need to answer about the specific tool of the graph above. only where I can do this? for example what theme of R, Python or Power Bi. I am able to do this for a line chart?
