# Task 1: Reflection

Put your reflection here


# Task 2: World map

```{r load-libraries-data, warning=FALSE, message=FALSE}
library(tidyverse)
library(sf)

# Load and clean internet user data
internet_users <- read_csv("data/share-of-individuals-using-the-internet-1990-2015.csv") %>%
  # Rename country code column to ISO_A3 so it matches what's in the Natural Earth shapefile
  rename(users = `Individuals using the Internet (% of population) (% of population)`,
         ISO_A3 = Code)

# Load world shapefile from Natural Earth
# https://www.naturalearthdata.com/downloads/110m-cultural-vectors/
world_shapes <- read_sf("data/ne_110m_admin_0_countries/ne_110m_admin_0_countries.shp")
```

```{r combine-shapefile-internet-users}
# Only look at 2015
users_2015 <- internet_users %>%
  filter(Year == 2015)

users_map <- world_shapes %>%
  left_join(users_2015, by = "ISO_A3") %>%
  filter(ISO_A3 != "ATA")  # No internet in Antarctica. Sorry penguins.
```

Make a map showing the proportion of individuals in each country that had access to the internet in 2015.

```{r plot-2015-internet-uses}
# TODO: Make a map of internet users with ggplot() + geom_sf()
```
