Question

我从某个网站获得了这个旭日形图代码，我非常喜欢它，我想让它符合我的需求。它比我现在所做的要复杂得多，所以我不知道如何做出我想要的某些改变。我一直在谷歌的帮助下尝试各种各样的东西，但我无法让它发挥作用。有一些JSON文件需要完成，但这不是问题。无论如何，我想做出以下更改：

1）所有文字都是180度，不要改变圆圈的程度

2）内圈的3个部分大小相同（蛋白质，Ugljikohidrati，Masti），然后当我们为内圈的下列元素（Biljni izvori，Zivotinjski izvori，Suplementi）输入一个（例如：蛋白质）时同样大小。所有内部部件始终具有相同的尺寸，直到我们到达最外部部分，该外部部分基于单个元件的值而被设计为不同的尺寸。我尝试将尺寸放在父母身上，但没有做任何事。

3）适合分区的文本。是的，即使对于初学者来说这也是一件非常简单的事情，但每当我尝试以某种方式改变它时，我最终会弄乱其余的代码。
