@Chrisir I want to work with data visualization on the globe, and my work is very similar to mapping these earthquake data on the globe, but I cannot load any CSV file into it.

Hello,

Try this:
table = loadTable("https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/significant_day.csv", "header");

:)

Hi @glv I initially tried the same thing but still it is showing the same error.

Hello,

Both of these work for me:

table = loadTable("https://earthquake.usgs.gov/earthquakes/feed/v1.0/summary/significant_day.csv", "header");

I downloaded and put in the sketch folder in /data:

table = loadTable("significant_day.csv", "header");

Try running this in Processing on the desktop.

You may not be able to access data from from a URL in OpenProcessing; I have not been able to last time I tried.

Processing can be downloaded from here:

There are also resources on the website to help you.

Loading resources from URL used to be fine and dandy, but nowadays, they are blocked by CORS (the headers at the server end).

Your code runs fine in the Desktop IDE.
