Requirements\n\n推奨する開発環境の構築手順に必要なものは次のとおりです：\n\n- GitHub Desktop\n- Visual Studio Code\n- Remote Development Extension Pack\n- Docker\n\n## 📦 4. Installation\n\n### 4.1. Clone the repository\n\nGitHub Desktop でリポジトリをクローンしてください．\n\n### 4.2. Open in Visual Studio Code\n\nリポジトリを Visual Studio Code で開いてください．\n\n### 4.3. Open Remote Container\n\nVisual Studio Code でリポジトリを開いたら，右下に表示されるポップアップから「コンテナーで再度開く」というボタンを選択してください．\nもしポップアップが表示されない場合は，左下の「\u003e\u003c」アイコンをクリックして「コンテナーで再度開く」を選択してください．\nこれにより自動で開発環境が構築されます．\n\n## 🚀 5. Usage\n\n### 5.1. Download Google Fonts\n\nGoogle Fonts のフォントをダウンロードします．\n次のコマンドを実行してください．\n\n```bash\nsh download.sh\n```\n\n### 5.2. Build the Skrifa extension (first run only)\n\nRust 製の Skrifa バックエンドをビルドし，Python から利用できるようにします．\n初回のみ，次のコマンドを実行してください．\n\n```bash\nuv run maturin develop --release\n```\n\n### 5.3. Generate Heatmap\n\nヒートマップを生成します．\n次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/coverage_jointplot.py\n```\n\n生成したヒートマップは `output` ディレクトリに保存されます．\n\n### 5.4. (Optional) Bonus Plots\n\nおまけで以下の可視化も用意しています．\n\n**Outline Length Histogram**：アウトラインの描画コマンド長の分布を確認するには次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/outline_len_histplot.py\n```\n\n**Outline Length / Path Count Jointplot**：横軸にアウトライン長，縦軸にパス数（`closePath` コマンド数）を取った joint plot を描くには次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/outline_len_path_jointplot.py\n```\n\n**UPEM Count Plot**：フォントごとの unitsPerEm の頻度を調べるには次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/upem_countplot.py\n```\n\n**Weight Count Plot**：フォントの `usWeightClass` の分布を見るには次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/weight_countplot.py\n```\n\n**Outline Command Bar Plot**：アウトライン描画コマンドの種類ごとの総数を確認するには次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/outline_command_barplot.py\n```\n\n**Outline Coordinate Joint Plot**：グリフアウトライン上の座標分布を joint plot で可視化するには次のコマンドを実行してください．\n\n```bash\nuv run google_fonts_heatmap/outline_coord_jointplot.py\n```\nランダムサンプルした描画コマンドの引数の X 座標・Y 座標をヒストグラムとしてプロットし，頻度の高い領域を確認できます．\n\n## 📑 6.
