this is for holding javascript data
<div> This is an example of an adjacency matrix. We can see that vertex <span class="ltx_Math" contenteditable="false" data-equation="1">\(1\)</span> is adjacent to vertex <span class="ltx_Math" contenteditable="false" data-equation="2">\(2\)</span> and <span class="ltx_Math" contenteditable="false" data-equation="3">\(3\)</span> therefore, they get a <span class="ltx_Math" contenteditable="false" data-equation="1">\(1\)</span> placed in their position and a <span class="ltx_Math" contenteditable="false" data-equation="0">\(0\)</span> in any other vertex. <br></div>
