title: Are there any tools for easily creating structure charts?
body: <p>I need to create a <a href="https://en.wikipedia.org/wiki/Structure_chart" rel="nofollow noreferrer">structure chart</a> as part of a school assignment, but all the normal chart and graph creation programs I have used such as <a href="https://www.yworks.com/products/yed" rel="nofollow noreferrer">yEd</a> and <a href="https://draw.io/" rel="nofollow noreferrer">draw.io</a> lack the symbols needed.</p>
  <p>Does anyone know of any similar programs that can be used to create a structure chart?</p>
