我一直在試驗SVG，並且想根據我得到的數據動態地將元素插入到SVG元素中。動態插入項目到SVG元素
所以說，在數據中，我有2行，每行5列。
我需要在SVG元素中繪製10 （2 * 5）項（rect,polygon等）。
例如：#表示svg元素邊界。
########### #######
#1 2 3 4 5# #12345#
#1 2 3 4 5# #12345#
########### #######
rect polygon
我能解決rect，但不過，似乎無法理解如何去其他形狀。
請問如何解決這個問題請幫忙。謝謝。
注意：如果使用某些庫可以提供幫助，請推薦，因爲我不知道是否可以使用現有的庫。
Here這是一個小提琴。 下面是rect填充元素的代碼：

for (var i in attrs)
el.setAttribute(i, attrs[i]);
return el;
};
// This will create a group in which the items will be filled.
var grp = drawShape('g');
svg.appendChild(grp);
// this is the data, according to which the block needs to be filled.
var items = ['xava|xav2|xav3|xav4|xav5|xav6|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|x2a4', 'xvvv|x2v2|xav3|xav4|xav5|xav6|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xav3|xav4|xav5|xav6|xav7|xav8|x2v9|x2av|x2aa|x2a2|x2a3|x2a4', 'xvvv|xvvv|x2v3|x2v4|x2v5|x2v6|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xvvv|x2v4|x2v5|xav6|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xvvv|xvvv|x2v5|xav6|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xvvv|xvvv|xvvv|x2v6|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xvvv|xvvv|xvvv|xvvv|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xvvv|xvvv|xvvv|xvvv|xav7|xav8|xav9|xaav|xaaa|xaa2|xaa3|xaa4', 'xvvv|xvvv|xvvv|xvvv|xvvv|xvvv|xvvv|x2v8|x2v9|x2av|xaaa|xaa2|xaa3|xaa4'];
