Fixed "Cannot read properties of undefined (reading 'arrayToDataTable')"
error caused by calling Google Charts API before it finished loading.
Changes:
- Move google.load() call below function definitions
- Use callback parameter to ensure charts load after library is ready
- Add guard check in drawChart2() to verify google.visualization exists
- Wrap chart drawing in $(document).ready() within the callback
This ensures the visualization library is fully loaded before attempting
to create charts, preventing race condition errors.
