@TriMyData @consult_ant @NINGN418 @data_ek @kfurdell @LopezAmandaM @VizWizBI Thanks a lot for providing another very interesting dataset and choosing my viz as one of your favorites! I was very pleased and learned a lot about Tableau.
Congratulations to all other participants! Really enjoyed to see all those different approaches this week.

Updated this week's #MakeoverMonday viz. Not so easy to keep track of the whole Brexit storyline :) #MMVizReview #DataFam

My submission for #MakeoverMonday week 13 puts the decline of UK post-Brexit exports to the EU into perspective with the total UK exports of goods. Is it really a decline or just a shift to Non-EU countries?

Feedback appreciated.

Thanks a lot for the viz review @TriMyData and @p_padham! I thinned the lines a bit (as mentioned in the review) and made a few more adjustments with colours and text. #MakeoverMonday

@laila_wendel Looks great! I really like the way you grouped the countries. This makes it obvious that Northern European countries are way ahead in that matter. I'd prefer the order N-W-E-S from a geographical point of view, but that might be just a personal preference.

[Valentin Kästner @ValentinKastner]

As a general warning: this week's #MakeoverMonday dataset contains seasonally adjusted annual rates. Summing these up in order to show yearly totals exaggerates the actual yearly expenditures by a factor of 12. Better use the average instead.

[Valentin Kästner @ValentinKastner]

@YusukeNakanish3 That's because the provided dataset is not inflation-adjusted. If you download real rather than nominal expenditures from the U.S. Bureau of Economics website, you would come to a different conclusion, I guess. I like the colorfulness of your viz, but I'm not sure what it means.

[Valentin Kästner @ValentinKastner]

@Jan_alysis Got it, thanks! To my eyes this looks better now, too :)

[Valentin Kästner @ValentinKastner]

My first ever #MakeoverMonday submission (2021 Week 12). Feedback is very welcome!

@followIndoPr0 @NerdyAndQuirky Nice viz! I also noted that when analyzing the data. While I would not accuse the graph creator of having bad intentions, it surely is misleading and does not draw the whole picture.

[Valentin Kästner @ValentinKastner]

@Jan_alysis Very appealing viz with nice explanations and clear instructions. You probably have tried it yourself, but is there a way to remove the unused ranks 0 and 12?
