Flowing Data have announced a new Visualise This challenge. Here’s my response:
You will notice that it is similar to the original. Why? As Nathan says in the challenge, the chart isn’t too bad. I chose to clear things up in order to emphasise the story. The original was too busy and the rise of the internet at the expense of other media was concealed by noise. Breaking the chart into small multiples in this case wouldn’t show this message as clearly as overlayed lines would. Making a stacked line/area chart also wouldn’t work because respondents were allowed to choose multiple answers.
Update: I added a baseline tab so that you can see the change of sources relative to a single one in response to Matt’s comment. I hoped this would emphasise Internet’s growth relative to the others. I;m not convinced this is better than the first worksheet. Why? Because the viewer has to do a little more thinking in order to understand the story.
