The bar graph was calling drawChart3() before Google Charts library
finished loading, causing "Cannot read properties of undefined
(reading 'arrayToDataTable')" error.
Applied same fix as performance page:
- Check if visualization already loaded before calling google.load
- Use callback parameter to ensure charts only draw after load
- Add flag to prevent duplicate library loads
- Guard against missing DOM elements
- Handle AJAX-loaded partial context
Fixes dashboard statistics bar graph view errors.
