Quick start

1. Import in your project PointlineJS:

          
            import { PointlineJS } from "pointlinejs";
            const simple_chart_config = {
              chart: {
                  container: "#tree-simple"
              },

              nodeStructure: {
                  text: { name: "Parent node" },
                  children: [
                      {
                          text: { name: "First child" }
                      },
                      {
                          text: { name: "Second child" }
                      }
                  ]
              }
            };
            const test = new PointlineJS(simple_chart_config);
            test.getTree();
            test.draw();

2. Add div in your html. Example based on index.html:

          
            <!DOCTYPE html>
            <html>
              <head>
                <meta charset="utf-8" />
                <title>PointlineJS Example</title>
              </head>
              <body>
                  <div id="tree-simple" style="height: 600px; width: 900px"></div>
              </body>
            </html>
