<script src="https://code.highcharts.com/modules/series-label.js"></script>
<script src="https://code.highcharts.com/modules/exporting.js"></script>
<script src="https://code.highcharts.com/modules/export-data.js"></script>

    <div id="container"></div>
    <p class="highcharts-BrAHMAdescription">

</figure>

Now, Create a CSS file for styling of the Line chart

.highcharts-figure,
.highcharts-data-table table {
    min-width: 360px;
    max-width: 800px;
    margin: 1em auto;
}

.highcharts-data-table table {
    font-family: Verdana, sans-serif;
    border-collapse: collapse;
    border: 1px solid #ebebeb;
    margin: 10px auto;
    text-align: center;
    width: 100%;
    max-width: 500px;
}

.highcharts-data-table caption {
    padding: 1em 0;
    font-size: 1.2em;
    color: #555;
}

.highcharts-data-table th {
    font-weight: 600;
    padding: 0.5em;
}

.highcharts-data-table td,
.highcharts-data-table th,
.highcharts-data-table caption {
    padding: 0.5em;
}

.highcharts-data-table thead tr,
.highcharts-data-table tr:nth-child(even) {
    background: #f8f8f8;
}

.highcharts-data-table tr:hover {
    background: #f1f7ff;
}

After that, create a JS file for showing data in Line chart

Highcharts.chart('container', {

    title: {
        text: 'Basic Line Chart'
    },

    subtitle: {
        text: 'Created by Brahma Prakash Shukla'
    },

    yAxis: {
        title: {
            text: 'Number of Employees in IT Department'
        }
    },

    xAxis: {
        accessibility: {
            rangeDescription: 'Range: 2010 to 2020'
        }
    },

    legend: {
        layout: 'vertical',
        align: 'right',
        verticalAlign: 'middle'
    },

    plotOptions: {
        series: {
            label: {
                connectorAllowed: false
            },
            pointStart: 2010
        }
    },

    series: [{
        name: 'Developers',
        data: [43934, 48656, 65165, 81827, 112143, 142383,
            171533, 165174, 155157, 161454, 154610]
    }, {
        name: 'Designers',
        data: [24916, 37941, 29742, 29851, 32490, 30282,
            38121, 36885, 33726, 34243, 31050]
    }, {
        name: 'Testers',
        data: [11744, 30000, 16005, 19771, 20185, 24377,
            32147, 30912, 29243, 29213, 25663]
    }, {
        name: 'Operations & Maintenance',
        data: [null, null, null, null, null, null, null,
            null, 11164, 11218, 10077]
    }, {
        name: 'Other',
        data: [21908, 5548, 8105, 11248, 8989, 11816, 18274,
            17300, 13053, 11906, 10073]
    }],

    responsive: {
        rules: [{
            condition: {
                maxWidth: 500
            },
            chartOptions: {
                legend: {
                    layout: 'horizontal',
                    align: 'center',
                    verticalAlign: 'bottom'
                }
            }
        }]
    }

});
