I am trying to use dygraph for javascript.
<html>
<head>
<script type="text/javascript"
src="dygraph-combined.js"></script>
</head>
<body>
<div id="graphdiv2"
style="width:500px; height:300px;"></div>
<script type="text/javascript">
g2 = new Dygraph(
document.getElementById("graphdiv2"),
"C:/temperatures.csv", // path to CSV file ***This file is local file in my C: drive***
{} // options
);
</script>
</body>
temperatures.csv is a local file on my machine. I read couple of posts that state .csv file has to be on a remote machine. I wonder is there a way to read local .csv file. Can you suggest some solution to this please. Thanks.

In general, you cannot load local files via JavaScript. This would be a huge security hole.
If you want to enable this for local development, you can run Chrome with the --allow-file-access-from-files
command-line flag. I assume other browsers have similar options. You may also need to add a "file://" before the "c:\" in your path.
Alternatively, consider spinning up a lightweight HTTP server for local development. Common choices are Python's http.server
(run python -m http.server
) or the http-server node module.

This works fine for me on Firefox with the CSV file in the same directory as the HTML file. Then just open the HTML file locally as a file://whatever and pass "input.csv" to dygraphs.
No turning off of security options needed - but I don't know about Chrome.
