js绘制超炫酷3D化学元素周期表

化学元素周期表(Periodic table of elements)是根据原子量从小至大排序的化学元素列表。列表大体呈长方形，某些元素周期中留有空格，使特性相近的元素归在同一族中，如碱金属元素、碱土金属、卤族元素、稀有气体，非金属，过渡元素等。这使周期表中形成元素分区且分有七主族、七副族、Ⅷ族、0族。由于周期表能够准确地预测各种元素的特性及其之间的关系，因此它在化学及其他科学范畴中被广泛使用，作为分析化学行为时十分有用的框架。
俄国化学家德米特里·伊万诺维奇·门捷列夫（Dmitri Mendeleev）于1869年总结发表此周期表（第一代元素周期表），此后不断有人提出各种类型周期表不下170余种，归纳起来主要有：短式表（以门捷列夫为代表）、长式表（以维尔纳式为代表）、特长表（以波尔塔式为代表）；平面螺线表和圆形表（以达姆开夫式为代表）；立体周期表（以莱西的圆锥柱立体表为代表）等众多类型表。

化学元素是构成这个世界的基石，也是无数科学工作者的梦幻表格。我对这种东西很感兴趣，偶尔看到一个超炫酷的js绘制的化学元素周期表，跟大家分享一下，下面是效果图：
