Good work, and thanks for sharing...trying to re-create (exactly in your case) another Viz in Tableau is a great way to learn.
I think your version is far easier (than the original) to see what the Viz is saying...btw here is an interesting blog defending the blanket rejection of all pie-charts! www.datavizmyths.com (which has some merits), however in this case I think the bars are far more quickly digested (by me anyway).
I did have a quick play with your version, and came up with this slight change (I have a general preference for horizontal bars...but this is a personal choice!)...let me know what you recon?
Thanks for your review Simon. I think that the horizontal bar works for this viz just as well as the vertical. I tend to default to horizontal bars myself, especially when scrolling might come in to play. I like it.
I eventually blogged about my experience and had something the similar to say about pie charts.
Now an aside on pie charts, I have a soft spot for pie charts. I mean how could anything named after such a perfect food be that bad. To brow from programing, I feel like they are the GO TOs of visualizations; they can be extremely powerful but they are far to easy to misuse and it is better to avoid them then to used them the wrong way.
So I appreciate the link to a similar point of view. It is always good to know that yo are not the only one who thinks a particular way, helps me know I am not crazy.
