What is Chart Generator?
Instead of struggling with heavy spreadsheet software to visualize simple data, this web utility turns comma-separated text into professional graphics instantly. By leveraging the Chart.js rendering engine directly in your browser, this graph maker dynamically builds scalable visual representations from raw input values. For example, typing "Revenue, 500" automatically maps the string to a category label and the number to a proportional data point along the Y-axis.
