               <div> Automated machine learning (AutoML) is the process of automating the tasks of 
        applying machine learning to real-world problems. AutoML covers the complete pipeline from the raw dataset to the deployable machine learning model. AutoML was proposed as an artificial intelligence-based solution to the ever-growing challenge of applying machine learning.The high degree of automation in AutoML allows non-experts to make use of machine learning models and techniques without requiring them to become experts in machine learning. Automating the process of applying machine learning end-to-end additionally offers the advantages of producing simpler solutions, faster creation of those solutions, and models that often outperform hand-designed models. AutoML has been used to compare the relative importance of each factor in a prediction model.</div>

CSV Viewer code beings

     <div class="container" style="padding:10px 10px;">
    <div id="header"></div>
    <div class="well">
        <div class="row">
        <form class="form-inline">
            <div class="form-group">
              <input type="file" id="files" name="file1"  class="form-control" accept=".csv" required />
            <div class="form-group">
             <button type="submit" id="submit-file" class="btn btn-primary">Upload File</button>
        <div class="row"
            <div class="row" id="parsed_csv_list">
A button which will render to next page
  <div class="form">
    <form action="/uploader" method="POST" enctype="multipart/form-data">
        <div class="Upload">
          <br> <button  type="submit" id="submit-file" >Next Page</button>

** Being of Javascript : this code is written for Csv viewer

<script type="text/javascript">
            config: {
                delimiter: "auto",
                complete: displayHTMLTable,
            before: function(file, inputElem)
                //console.log("Parsing file...", file);
            error: function(err, file)
                //console.log("ERROR:", err, file);
            complete: function()
                //console.log("Done with all files");
    function displayHTMLTable(results){
        var table = "<table class='table'>";
        var data = results.data;
            table+= "<tr>";
            var row = data[i];
            var cells = row.join(",").split(",");
                table+= "<td>";
                table+= cells[j];
                table+= "</th>";
            table+= "</tr>";

        table+= "</table>";
