Plotlyを使う人にも家族がいることを、私たちは忘れていません。

はじめに

スーパーでブロッコリーを見るとPlotlyを連想する病気にかかっています。
自分の作業用によく使うPlotlyの使い方をまとめたので公開します。
実際にグリグリ動かしたい方はkaggleのkernelにアップしてるのでそちらでグリグリしてください。

※ちなみにPlotlyの3Dグラフをグリグリしたことがない人は、是非とも一度グリグリした方がいい。感動する。

データロード

データはseabornから
iris,titanic,flightsの3つを適宜使用する。

flights_data = sns.load_dataset('flights')

iris_data.head()

最後に

Plotlyは確かに綺麗なグラフが描けるんだけど、コーディングが結構煩雑になりやすい。
コーディングミスにも気を配る必要が出てくるから、特にこだわりが無いならSeaborn使った方が早いし無難かなと感じる。
会議とか見せ方を工夫したいときには、Plotly使うといいと思う。
