這是我的d3.js版本4(基於v3中的this chart)的和絃圖。你可以運行它,或只是看看圖片:如何將標籤添加到d3.js中的和絃圖的圓弧中

我試圖按照這個例子:http://bl.ocks.org/syntagmatic/9eadf19bd2976653fa50,也發現了類似的主題在這裏:d3.js Add labels in Chord diagram
然而,我無法將我的頭圍繞如何將其整合到我的代碼中。任何幫助真的很感激。
太謝謝你了!只需一個簡短的後續問題/註釋:https://developer.mozilla.org/en-US/docs/Web/SVG/Attribute/xlink:href states xlink已被棄用。我只保留了'''href''',它似乎也能工作。 –
最後說明:如何將文本居中?感謝你的幫助 :) –
