I'm using version Django==5.0.6 and attempting in integrate charts using chartjs and plugin datalabels.

When I use the charts render without issue, but I'm not able to see any datalabels.

If I try to add Chart.register(ChartDataLabels); the graph no longer renders. I've also tried Chart.plugins.register(ChartDataLabels);

I'd like to be able to use the most updated version of chartjs but when I change the chart version to anything other than 2.9.3, the graphs don't render.

        options: {
          responsive: true,
          title: {
             text: "Job outcome data",
             display: true
          },
          scales: {
             xAxes: [{
               ticks: {
                     beginAtZero:true
                 }
     
             }],
           yAxes: [{ stacked:true}]
           
         },
         plugins: {
          datalabels: {
            align: 'end',
            color: 'red',
        } /* added for simplicity to test */
        }         
     }     
     });    
</script>
{% endblock %}

Ideally I'd like to be able to use the most up to date,s table version of chartjs. The graph renders with 2.9.3, but I can't register datalabels.
