You should open script tag (top or end of your Blade template) and pass your data to JS script.
I usually use @stack. Your code should be like this:
master.blade.php
<!DOCTYPE html>
<html lang="en">
<head>
    <title>@yield('title')</title>
</head>
<body>
    Blah Blah Blah
    <!-- Start Content -->
    @yield('content')
    <!-- End Content -->
    <!-- Custom Scripts -->
    @stack('scripts')
</body>
</html>
chart.blade.php
@extends('master')
@section('content')
    Your Page Content
@endsection
@push('scripts')
    <script>
        var pie = {
            data: [{
                name: 'Car',
                y: 56.33,
                sliced: true,
                selected: true,
                url: "{{route('dashboard')}}"
            }]
        };
    </script>
@endpush
By this way, your data will be replaced with Laravel helper functions.
