How to check if data is hierarchical in d3.js?

@orpha 

In D3.js, you can check if data is hierarchical by using the .children property of the data object. Hierarchical data typically has a nested structure where each parent node has child nodes.

To check if data is hierarchical, you can use the following code snippet:

 1
 2
 3
 4
 5
 6
 7
 8
 9
10
11
12

// Assume 'data' is your dataset

function isHierarchical(data) {
  return data.hasOwnProperty('children');
}

// Check if data is hierarchical
if (isHierarchical(data)) {
  console.log("Data is hierarchical");
} else {
  console.log("Data is not hierarchical");
}

This function checks if the data object has a property called 'children'. If it does, then the data is considered hierarchical. You can modify this function to check for other hierarchical data structures as well.
