In terms of flexibility and performance for data visualization with tools like Highcharts, is it better to store data in a JSON file or a SQLite database in PHP?

When it comes to flexibility and performance for data visualization with tools like Highcharts in PHP, storing data in a SQLite database is generally better than using a JSON file. SQLite databases are optimized for querying and handling large datasets efficiently, which can improve performance when retrieving data for visualization. Additionally, using a database allows for more complex queries and data manipulation, providing greater flexibility in how the data can be displayed in the visualization. 

// Connect to SQLite database
$db = new SQLite3('data.db');

// Query data from database
$results = $db->query('SELECT * FROM data_table');

// Fetch data and convert to JSON
$data = array();
while ($row = $results->fetchArray(SQLITE3_ASSOC)) {
    $data[] = $row;
}

// Close database connection
$db->close();

// Output JSON data for Highcharts
echo json_encode($data);
