| We can import it more easily via [CartoDB's cached infrastructure](http://eschbacher.cartodb.com/api/v2/sql?q=SELECT%20the_geom,unique_key,created_date,closed_date,agency,agency_name,complaint_type,descriptor,location_type,incident_zip,incident_address,street_name,address_type,city,status,due_date,resolution_action_updated_date,latitude,longitude,borough,community_board%20FROM%20nyc_rat_sightings&format=csv&filename=nyc_rat_sightings) | ||

This section might be good for the postgis/sql cheat sheet. We might also look at where else to suggest this information. But it doesn't fit here since it's so late in the course.

Looking good so far, @mehak-sachdeva. What do you think about adding an additional section that normalizes the rat sightings by the number of people in each borough? We can get that data from the Data Observatory API. |
| num_sightings DESC | ||

| Proportional symbol maps symbolize attributes by having the marker have an area proportional to a quantity -- in our case that's number of complaints. In our case, we know roughly that the max number of complaints in any of the boroughs is around 6000, so we normalize all years by that number and then take the square root (since area is proportional to r^2). |

Let's use HTML to make the r^2 a superscript instead (r<sup>2</sup>)
|
Did most of the formatting and file/site linking changes as suggested. Making a new map now and will look to incorporate the normalization by number of people in each borough with DO and add that section subsequently. Also thinking of a better lesson name alongside. |
|
For the naming, I suggest using some terms that are important in the lesson: group by, aggregate, postgis, join, dates, strings, rats, etc. etc. :) it'll be a crazy name! |
|
@mehak-sachdeva, what's the status here? seems like it's almost ready to be merged? |
|
@ohasselblad - still need to add the DO part to the map and subsequently to the lesson. Should be able to do this by EOD today. |
|
I'd say let's hold off on the DO extension to this until later! We can add it as a separate chapter. Maybe create a ticket and assign for after the DO lessons come out? |
|
Yes, I feel that does make more sense. Okay - let me proof everything once and link the map that I have (without the DO) and then we can merge it! |
|
@ohasselblad relinked to the map in documentation account. Good to go? |

Course sql and postgis in CARTO - lesson 4 - Intermediate SQL
There could be some styling oversights - let me know if this fits in well.
