I am concerned about a lack of clarity regarding the requirements for the second part
of Task 2.

The specifications state only "the other visualisations should present some more
insightful information, such as any URLs that are 'trending' across the week, or
more meaningful descriptions of the locations from which requests are made."

My first question is what is a "trending URL"?  I do not understand what this means 
exactly and I need  specific information about what is to be computed and plotted.

I have performed searches on Google for "trending URL" but only found references to
trending tags, trending searches and similar things.  In any case, as I understand 
from what I read, the notion of trending X (whatever X is) relates to anomaly 
detection; and every Internet platform seems do it that differently and their 
algorithms are proprietary. 

I also do not understand what is meant by "more meaningful descriptions of the
locations from which requests are made". This seems even more unclear than the
trending URLs suggestion: I did not even know how to formulate a search query
for it.

Can I have more specific information for a suitable task, or tasks, for the second
that would be acceptable?

You're given some freedom to choose what and how you want to display;  in previous years (when a similar task asked 
for more examples0, students appreciated that the task was no so prescriptive.

All are just examples of something that is increasing;  in our case, we have data across just one week.  Was the use 
of any particular URLs significantly increasing over the week?  URLs often embed search terms, and these are often 
reported as trending (becoming increasingly popular over a short time).

(here's an amazing example of an online Calculus exam in the US, in which students were permitted to use Google 
searches during the exam:

But that was just a suggestion.

Each request in the weblog has a recorded IP adresss (the first field).  Most are from the same IP address (a proxy 
server), but others are could give away the physical location from where the request was made (there are some free 
web-services to roughly map IP addresses to location).

But, again, just a suggestion.
