How is it possible to make curved bar chart or curved column charts in chart.js?

You could do this with a line chart as illustrated in below code sample, which needs to be further improved to obtain the result you expect. 

new Chart(document.getElementById('myChart'), {
    type: 'line',
    data: {
        labels: [1, 2, 3, 4, 5, 6, 7],
        datasets: [
          {
              data: [0, 5, 0, 0, 0, 0, 0],
              fill: true,
              backgroundColor: 'rgb(255, 0, 0, 0.7)',
              backgroundColor: 'rgb(255, 0, 0, 0.7)',
              lineTension: 0.4,
              pointHitRadius: 0
          },
          {
              data: [0, 0, 9, 0, 0, 0, 0],
              fill: true,
              backgroundColor: 'rgb(255,165,0, 0.7)',
              backgroundColor: 'rgb(255,165,0, 0.7)',
              lineTension: 0.6,
              pointHitRadius: 0
          },
          {
              data: [0, 0, 0, 6, 0, 0, 0],
              fill: true,
              backgroundColor: 'rgb(255, 215, 0, 0.7)',
              backgroundColor: 'rgb(255, 215, 0, 0.7)',
              lineTension: 0.6,
              pointHitRadius: 0
          },
          {
              data: [0, 0, 0, 0, 5, 0, 0],
              fill: true,

              lineTension: 0.6,
              pointHitRadius: 0
          },
          {
              data: [0, 0, 0, 0, 0, 4, 0],
              fill: true,
