Create a chart

Note: This guide assumes that you have some basic web development knowledge of HTML, JS, CSS and git.

Create a new HTML file with some basic setup and include the picasso.js bundle:

<!DOCTYPE html>
<html>
  <head>
    <title>My picasso.js page</title>
    <script src="https://unpkg.com/picasso.js"></script>
    <style>
      html,
      body {
        margin: 0;
        padding: 0;
        height: 100%;
      }
      #container {
        height: 100%;
        position: relative;
      }
    </style>
  </head>
  <body>
    <div id="container"></div>
    <script>
      /* PLACE CODE HERE */
    </script>
  </body>
</html>

In the script tag, initiate a picasso chart instance:

<script>
  picasso.chart({
    element: document.querySelector('#container'), // This is the element to render the chart in
    data: [
      {
        type: 'matrix',
        data: [
          ['Month', 'Sales', 'Margin'],
          ['Jan', 1106, 7],
          ['Feb', 5444, 53],
          ['Mar', 147, 64],
          ['Apr', 7499, 47],
          ['May', 430, 62],
          ['June', 9735, 13],
          ['July', 5832, 13],
          ['Aug', 7435, 15],
          ['Sep', 3467, 35],
          ['Oct', 3554, 78],
          ['Nov', 5633, 23],
          ['Dec', 6354, 63],
        ],
      },
    ],
    settings: {
      scales: {
        x: { data: { field: 'Margin' } },
        y: { data: { field: 'Sales' } },
      },
      components: [
        {
          // specify how to render the chart
          type: 'axis',
          scale: 'y',
          layout: {
            dock: 'left',
          },
        },
        {
          type: 'axis',
          scale: 'x',
          layout: {
            dock: 'bottom',
          },
        },
        {
          type: 'point',
          data: {
            extract: {
              field: 'Month',
              props: {
                x: { field: 'Margin' },
                y: { field: 'Sales' },
              },
            },
          },
          settings: {
            x: { scale: 'x' },
            y: { scale: 'y' },
            size: function () {
              return Math.random();
            },
          },
        },
      ],
    },
  });
</script>

You should now see a very basic bubble plot.
