Я построил диаграмму на веб-странице с помощью программы JavaScript Cytoscape. js. Он вообще ничего не отображает. Но это также не дает синтаксических ошибок, кроме предупреждения о захвате мыши для масштабирования.
Вот код:
<style type="text/css">
#cy {
width: 90%;
height: 300px;
display: block;
}
</style>
<script type="text/javascript" src="https://cdnjs.cloudflare.com/ajax/libs/cytoscape/3.14.0/cytoscape.min.js"></script>
<script type="text/javascript">
var cy = cytoscape({

Мой код фактически сгенерирован в asp. net, но это не должно иметь значения.
