Today, I'm returning to those "equal-area histograms" that Andrew wrote about last month. I have two previous posts about this. The first post introduces the concept: in a traditional histogram, the columns have the same bin width while the column heights can represent a variety of metrics, such as counts, relative frequencies (i.e. proportion of the data) and densities; in the equal-area histogra
今回の衆院選では「一票の格差」是正のため、19都道府県97選挙区で区割りが変更された。6県(青森、岩手、三重、奈良、熊本、鹿児島)では選挙区が各1つ削減され、有権者の構成が大幅に変わった。新しい区割りに基づいて過去の比例代表票を再集計し、選挙区ごとの横顔を見てみよう。 【結果に関する分析は「2017総選挙・有権者カルトグラム」に掲載しました】 保守王国は60選挙区前後 横軸で自民・公明の平均得票率を、縦軸に2000年以降6回の総選挙の得票率の変動(統計学的な指標「平方和」で、平均との差の二乗を合計したもの)を表すと、全選挙区の分布は以下のようになる。 グラフの右下にある選挙区は、与党(自民と公明)の得票率が高く、得票率の変動も小さい「保守王国」だ。都市部はほとんどなく、有力政治家の地盤であることなどから、新しい政党がチャレンジしても結果につながらなかった。 変動の大きな選挙区は、政権交代が

Welcome to Visual Evidence, a new regular series about visualization in the real world! We’ll take a look at unexpected datasets, cool design solutions or insightful graphics. We’ll find examples of how visual information can help us solve real-world problems or save us from our own mistakes. And we’ll illustrate all these ideas with charts, sketches, and of course, plenty of gifs. Chances are, yo
The G-Econ research project is devoted to developing a geophysically based data set on economic activity for the world. The current data set (GEcon 4.0) is now publicly available and covers “gross cell product” for all regions for 1990, 1995, 2000, and 2005 and includes 27,500 terrestrial observations. The basic metric is the regional equivalent of gross domestic product. Gross cell product (GCP)
Edit: Buy the movie poster hues (1914-2012) poster A couple of weeks ago, I was having brunch with Kim-Mai Cutler — we were discussing the new startup I’m building in the enterprise space (if you’re a ui/ux person or awesome engineer looking for something fun to do, drop me a line!) — and I mentioned how I felt that most movie posters these days were very blue and dark.
