How to read a blob in d3.js?

To read a blob in d3.js, you can use the d3.blob() function to load a binary file as a blob object. Here is an example of how to read a blob in d3.js:

d3.blob("file.txt").then(function(blob) {
  // Create a new FileReader object
  var reader = new FileReader();

  // Define a function to handle the loaded blob
  reader.onload = function(event) {
    var data = event.target.result;
    console.log(data); // Print the contents of the blob
  };

  // Read the blob as a text string
  reader.readAsText(blob);
});

In this example, we use the d3.blob() function to load the file named "file.txt" as a blob object. We then create a new FileReader object to read the blob data. We define an onload function to handle the loaded blob data, in this case, we read the blob as a text string using the readAsText() method and log the contents of the blob to the console.
