simple js file to read iris data and format the numbers

readCsv2.js

// set the dimensions and margins of the graph
const margin = {top: 10, right: 30, bottom: 40, left: 70},
    width = 800 - margin.left - margin.right,
    height = 600 - margin.top - margin.bottom;

// append the svg object to the body of the page
const svg = d3.select("body")
    .append("svg")
    .attr("width", width + margin.left + margin.right)
    .attr("height", height + margin.top + margin.bottom)
    .append("g")
    .attr("transform", `translate(${margin.left},${margin.top})`);

d3.csv("data/iris.csv").then( function(data) {
    // clean/fix the data
    data.forEach(function(d) {
        d.sepal_width = +Number(d.sepal_width);
        d.sepal_length = +Number(d.sepal_length);
        d.petal_width = +Number(d.petal_width);
        d.petal_length = +Number(d.petal_length);
    });
    console.log(data)
