What best practices should be followed when working with timestamps and graph visualization in PHP using jpgraph?

When working with timestamps and graph visualization in PHP using jpgraph, it is important to properly format the timestamps for the x-axis of the graph to ensure accurate representation of time intervals. One best practice is to convert the timestamps into a readable date format using the PHP date() function before plotting them on the graph. This will make the graph more user-friendly and easier to interpret. 

// Sample code snippet to format timestamps for graph visualization using jpgraph
$timestamps = [1596153600, 1596240000, 1596326400, 1596412800]; // Sample timestamps
$dates = array_map(function ($timestamp) {
    return date('Y-m-d H:i:s', $timestamp);
}, $timestamps);

// Create a new graph
$graph = new Graph(800, 400);
$graph->SetScale('textlin');

// Create a line plot
$lineplot = new LinePlot([10, 20, 30, 40]);
$lineplot->SetLegend('Sample Data');
$graph->Add($lineplot);

// Set x-axis labels as formatted dates
$graph->xaxis->SetTickLabels($dates);

// Display the graph
$graph->Stroke();
