javascript - How to parse a local tsv variable on d3.js - Stack Overflow

I currently have the following:

d3.tsv(filename, function(error, data) {
    data.forEach(function(d) {
        d.date = parseDate(d.date);
        d.outside = +d.outside;
        d.house = +d.house;
});

That gets a tsv file and processes it with no issues. What I would like to do is to replace "filename" (which is a file) with a variable (such a string containing text in tsv format). How can I easily do this? Thanks!

You can use d3.tsv.parse() for this, e.g.

var data = d3.tsv.parse(string);

Actually, for example, you can obtain the string from a fetch query and then transform it to text so that later can be parsed with D3.js.

This is once loaded in your browser: https://d3js/d3.v5.min.js

var data = await fetch('/mytsv.tsv');
var mytsvstr = await data.text();
var tsvdata = await d3.tsvParse(mytsvstr);
