On the left, you see a variety of CGI scripts available from your directory. The output from these scripts gets sent to this frame. Study the source code behind the HTML forms and the source code for the CGI scripts.

To complete this assignment, improve wxplot.cgi to accomplish the following:

Plot more than one day of data (i.e., from a "start date" to an "end date") with the dates chosen by the user
Overlay the time series for temperature at two specified stations
Plot multiple variables from the same site on the same plot (e.g., temperature and dewpoint)

Then clean up your page to make it somewhat attractive and useful. Be creative. These instructions are repeated in the comments within wxplot.cgi.

Below is the output from userenv.cgi, executed through the use of an #include virtual statement directly within the HTML source. Look for REMOTE_ADDR and HTTP_USER_AGENT and notice how you compromise your privacy simply by accessing the server!

Time on the server: Sun May  5 07:44:56 2024

The CGI form has the following keys: []
The QUERY_STRING is: 
The STDIN is: 
The ARGV is: ['userenv.cgi']
