SVGElement: dataset プロパティ
Baseline
Widely available
This feature is well established and works across many devices and browser versions. It’s been available across browsers since 2018年4月.
dataset は SVGElement インターフェイスの読み取り専用プロパティで、要素のカスタムデータ属性 (data-*) への読み書きアクセスを提供します。これは文字列のマップ (DOMStringMap) を公開し、各 data-* 属性の項目を持つ文字列の地図（DOMStringMap）を公開します。
dataset の動作に関するより詳しい情報は HTMLElement.dataset を参照して下さい。
値
DOMStringMap です。
例
html
<div>
<svg viewBox="0 0 120 30" xmlns="https://www.w3.org/2000/svg">

Carina Anand
</text>
</svg>
</div>
