Im trying to draw a circle based on data from a weather api and when i try to draw the circle i keep getting an error. I don’t know how to fix the mistake so here is the code. If you know how to fix it could you please let me know.

```auto
let weather;

function setup() {
  createCanvas(400, 400);
  loadJSON('http://api.openweathermap.org/data/2.5/weather?zip=85248,us&units=imperial&appid=27b5b65946faf6311b0225a9c450b652', gotData, 'pjson');
}

function gotData(data) {
  weather = data;
}

function draw() {
  background(51);

  tempeture = weather.main.temp;
  console.log(tempeture);
}

```

First, `temperature` isn’t defined in the code you provided, make sure you include `let temperature;` at the top alongside `let weather;` (or `let weather, temperature;` to define both). That probably won’t throw an error though, so the error you’re most likely running into is that `weather` is still undefined on the first run through `draw()` because it hasn’t gotten the data yet (so trying to read `weather.main.temp` isn’t possible). You can solve that by making sure that `weather` has something in it before using it, like this:

```auto
if (weather) {
  tempeture = weather.main.temp;
  console.log(tempeture);
}

```
