   <title>Plotly.js Bar Chart Example</title>

   <script src=""></script>



   <div id="myDiv" style="width:600px;height:400px;"></div>


       var trace1 = {

           x: ['Category A', 'Category B', 'Category C'],

           y: [20, 14, 23],

           type: 'bar'


       var data = [trace1];

       var layout = {

           title: 'Bar Chart using Plotly.js',


       Plotly.newPlot('myDiv', data, layout);




This code snippet creates a simple bar chart within the division with id "myDiv". We define data for our bar chart in the `trace1` where the x-axis represents categories, and the y-axis shows the values. We use `Plotly.newPlot` to render the chart in our designated div. Adjust the `x` and `y` values as needed to fit your data. Explore more of Plotly.js to add more interactivity and customize your charts to your liking.
