What is @types/d3-dsv?
@types/d3-dsv provides TypeScript type definitions for the d3-dsv library, which is part of the D3.js suite. The d3-dsv library is used for parsing and formatting delimiter-separated values (DSV) such as CSV (comma-separated values) and TSV (tab-separated values).
What are @types/d3-dsv's main functionalities?
Parsing CSV
This feature allows you to parse CSV data into an array of objects. Each object represents a row, with properties corresponding to the column names.
const d3 = require('d3-dsv');
const csvData = 'name,age\nAlice,30\nBob,25';
const parsedData = d3.csvParse(csvData);
console.log(parsedData);
Formatting CSV
This feature allows you to format an array of objects into a CSV string. Each object represents a row, with properties corresponding to the column names.
const d3 = require('d3-dsv');
const data = [
{ name: 'Alice', age: 30 },
{ name: 'Bob', age: 25 }
];
const csvString = d3.csvFormat(data);
console.log(csvString);
Parsing TSV
This feature allows you to parse TSV data into an array of objects. Each object represents a row, with properties corresponding to the column names.
const d3 = require('d3-dsv');
const tsvData = 'name\tage\nAlice\t30\nBob\t25';
const parsedData = d3.tsvParse(tsvData);
console.log(parsedData);
