Hello sir, the files dose not display any location from csv file, please check once

i want to know how to add option input file (selected files by user) csv into leaflet.

// Read markers data from data.csv
$.get('./data.csv', function(csvString) {...});

i want to change path '.data.csv' to a path selected by user. Thank you so much.

Hi,

I was wondering if it were possible to input polygon data with a .csv file, the same way you show here with point data? If so, what would the formatting be link in both the .csv and the index.html?

Thank you,
Jeff

@ilyankou - Would you please look into this issue? I happened to notice it while finishing up the image log. Thanks!

Hi I tried your code but I encountered the following error:

Access to XMLHttpRequest at 'file:///Users/.../Documents/flask-leaflet/templates/data.csv' from origin 'null' has been blocked by CORS policy: Cross origin requests are only supported for protocol schemes: http, data, chrome, chrome-extension, chrome-untrusted, https.

What could be the problem?

In my case, no markers are displayed when opening the index.html locally in Chrome or Safari. Is there somebody who had the same problem and found a solution?

@ilyankou - I'm impressed how you've used Papaparse in leaflet heatmap, with the added benefit of displaying in the local computer Chrome browser with web security disabled.

You also discovered that leaflet-omnivore does not work in the local Chrome browser with web security disabled.

Would it be feasible to use Papaparse instead of omnivore in leaflet-map-csv? I believe it's our only HandsOnDataViz template that still uses omnivore.
