HTML Canvas is perfect for Scatter Plots
const xArray = [50,60,70,80,90,100,110,120,130,140,150];
const yArray = [7,8,8,9,9,9,10,11,14,14,15];
// Plot Scatter
ctx.fillStyle = "red";
for (let i = 0; i < xArray.length-1; i++) {
let x = xArray[i]*400/150;
let y = yArray[i]*400/15;
ctx.beginPath();
ctx.ellipse(x, y, 2, 3, 0, 0, Math.PI * 2);
ctx.fill();
}
const xMax = canvas.height = canvas.width;
const slope = 1.2;
const intercept = 70;
// Plot Line
ctx.beginPath();
ctx.moveTo(0, intercept);
ctx.lineTo(xMax, xMax * slope + intercept);
ctx.stroke();
let xMax = canvas.height;
let yMax = canvas.width;
let slope = 1.2;
let intercept = 70;
const xArray = [50,60,70,80,90,100,110,120,130,140,150];
const yArray = [7,8,8,9,9,9,10,11,14,14,15];
// Plot Scatter
ctx.fillStyle = "red";
for (let i = 0; i < xArray.length-1; i++) {
let x = xArray[i] * xMax/150;
let y = yArray[i] * yMax/15;
