Since your CSV
data has no header, you should use d3.text
to load the data, followed by d3.csvParseRows
to parse it to a JSON
array (see https://stackoverflow.com/a/13870360/2358409). To extract the data values from the JSON
array, you can use Array.map
.
data: d3.csvParseRows(types).map(v => v[1])
Please take a look at your amended code and see how it works.
d3.text("https://raw.githubusercontent.com/uminder/testdata/main/so/csv/donut.csv").then(makeChart);
function makeChart(types) {
new Chart('doughnut-chart', {
type: 'doughnut',
data: {
labels: ['Cancelled', 'Success', 'Failed'],
datasets: [{
label: 'Population (millions)',
backgroundColor: ['#3e95cd', '#3cba9f', '#8e5ea2'],
data: d3.csvParseRows(types).map(v => v[1])
}]
},
options: {
title: {
display: true,
text: 'Weekly Status'
}
}
});
}
