amcharts - Force Directed Tree - convert data Laravel PHP - laravel

Question

I am trying to display a force directed tree. There are 3 models
Company / Division / Department
Each Company has many divisions. Each division belongs to one Company.
Each Division has many departments. Each department belongs to one Division.
amcharts expects a syntax like:
[{
"name": "First",
"children": [{
"name": "A1", "value": 100
}, {
"name": "A2", "value": 60
}, {
"name": "A3", "value": 30
}]
}, {
"name": "Second",
"children": [{
"name": "B1", "value": 135
}, {
"name": "B2", "value": 98
}, {
"name": "B3", "value": 56
}]
}, {
"name": "Third",
"children": [{
"name": "C1", "value": 335
}, {
"name": "C2", "value": 148
}, {
"name": "C3", "value": 126
}, {
"name": "C4", "value": 26
}]
}, {
"name": "Fourth",
"children": [{
"name": "D1", "value": 415
}, {
"name": "D2", "value": 148
}, {
"name": "D3", "value": 89
}, {
"name": "D4", "value": 64
}, {
"name": "D5", "value": 16
}]
}, {
"name": "Fifth",
"children": [{
"name": "E1", "value": 687
}, {
"name": "E2", "value": 148
}]
}]
I am only able to get the first level here:
foreach ($companies as $company) {
$data[] =
(object) [
'name' => $company->name,
'value' => $company->value,
];
}
I am sure that I need to further iterate through $company->devisions and so on but not sure how to build the final construct amcharts is expecting. Any hints?

You can try something in the lines of:
$data = [];
foreach ($companies as $company) {
$childrenArray = [
'name' => $company->name,
];
foreach ($company->divisions as $division) {
$childArray['children'][] = [
'name' => $division->name,
'value' => $division->value,
];
}
$data[] = $childrenArray;
}
return json_encode($data);
