                geom_sf very slow with large sf objects using Mac OS quartz graphic device
              
          
    I am on a Mac (2016 MBP 15" with 16GB memory) and am testing out the development version of ggplot2 with sf plotting support.
Overall I am loving it, but I am finding geom_sf to be very slow when plotting larger sf polygons objects. I think I've narrowed it down to the quartz graphics device, which is much slower than X11 on these large objects (however quartz produces nicer graphics than X11).
I would be happy to just use X11 but I do like having plots appear in the plot pane in RStudio, and I believe the RStudio Graphics Device uses quartz on Mac OS and I don't think there's a way to change that.  So I'm not sure if this is really a ggplot2/sf issue or if it's a Mac quartz issue... or possibly even an RStudio issue, but I thought I would post it here first to see if others are experiencing the same thing.
I also did the same comparison with sf's plot method - there is still a large difference between X11 and quartz, however overall it is faster than ggplot2::geom_sf.

    Potential issues and workarounds when using Carto.js v3 with maps made with the Builder interface

When using the current version (v3 as of March 2017) of Carto.js with maps using Carto's new Builder interface, there are some issues you are likely to run into. Here I run through the common issues and some suggested workarounds.
Analysis and Widgets don't work

This is because Carto.js v3 doesn't understand them. Sorry but there is no easy workaround here. In the case of Analysis you could save it as its own layer and use that layer instead.
Legends don't work

                Responsive CartoDB choropleth linked to strip plot
              
          
    A choropleth map created in CartoDB.js linked to a D3.js strip plot. Open to view in full.
For now the link is only one way (hover/click on the map updates the strip plot). Data is also duplicated (it lives in CartoDB and in a csv).
Both map and plot are responsive and respond to resize. The map responsiveness comes from my block Responsive map with Cartodb/Leaflet.
Integretad live on tijd.be (Dutch) and on lecho.be (French).
