What are the differences between Highstock and Highchart in terms of data visualization and which one would be more suitable for displaying timestamp and value data from a SQL database?

Highstock is specifically designed for time-series data visualization, making it more suitable for displaying timestamp and value data from a SQL database. It includes features such as zooming, panning, and dynamic updates that are particularly useful for time-based data. On the other hand, Highcharts is a more general-purpose charting library that can also handle time-series data but may not have all the specialized features of Highstock for this type of data. 

// Sample PHP code using Highstock to display timestamp and value data from a SQL database

// Assuming you have fetched the timestamp and value data from your SQL database and stored them in $timestamps and $values arrays

$data = array();

for ($i = 0; $i < count($timestamps); $i++) {
    $data[] = array(strtotime($timestamps[$i]) * 1000, $values[$i]);
}

echo "<div id='container'></div>";

echo "<script>";
echo "Highcharts.stockChart('container', {
    rangeSelector: {
        selected: 1
    },
    series: [{
        name: 'Data',
        data: " . json_encode($data) . ",
        tooltip: {
            valueDecimals: 2
        }
    }]
});";
echo "</script>";
