How to use

Just copy this code and paste at - https://realtimehtml.com/

<script src="https://d3js.org/d3.v7.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/d3-org-chart@3"></script>
<script src="https://cdn.jsdelivr.net/npm/d3-flextree@2.1.2/build/d3-flextree.js"></script>
<div class="chart-container"></div>

<script>
 var chart;
 d3
  .csv(
   "https://raw.githubusercontent.com/bumbeishvili/sample-data/main/org.csv"
  )
  .then((data) => {
   chart = new d3.OrgChart().container(".chart-container").data(data).render();
  });
</script>

Installing

npm i d3-org-chart

import { OrgChart } from 'd3-org-chart';

 new OrgChart()
     .container(<DomElementOrCssSelector>)
     .data(<Data>) // https://github.com/bumbeishvili/sample-data/blob/main/data-oracle.csv
     .render();

In general, we encourage to look into the source code to understand how it works. The chart code is basically a single class. At the top of the class, we have a state object called attrs which stores the state of the org chart and each single property is overridable by the user.

For example, one of the property name inside attrs object is duration, which controls animation duration for chart, when expanding or collapsing nodes.

If we want to get the value, we can either do

chart.getChartState().duration

or directly

chart.duration()

chart in the above case is an instance of OrgChart class. We can get it using new OrgChart()

If we want to set property, we can pass argument to the same function and it will automatically set the value

chart.duration(3000)  // This will become very slow moving chart

You can see list of all properties , their description of what each property does in the actual source code.

Be aware that they are chainable, so if we wanted to set multiple properties, we would do this

const chart = new OrgChart()
                    .data(ourData)
                    .container(ourDomElementOrCssSelector)
                    .duration(ourDuration)
                    .render()


// We can keep chaining values in runtime
chart.data(updatedData).render()

Notes & appreciations

I created this org-chart when I was hired by TeamApps.

Although this Org chart was specifically created for teamapps java web application framework , it's very flexible and can be used in any environment, where d3 and DOM is accessible.

Big thanks to Matthias and Yann, who assembled requirements for org-chart and had valuable pieces of advice afterwads.

Also, thanks all people who made generous donations, it gives me motivation to further improve this org chart component.

Thanks contractzen for the significant contribution, which made implementation of some of the most important features (optimal layout, exporting ) possible.
