How is the data relational?

The headers of each table show the dataset name. The underlined variables are primary keys while all the others are foreign keys. The arrows show how the datasets are connected.

The diagram is built using the dm R package. The code can be found in data-raw/dm.R.

Examples

Data Wrangling

fec16 can be used to summarize data in order see how many candidates are running for elections (in all offices) for the two major parties:

library(dplyr)

data <- candidates %>%
  filter(cand_pty_affiliation %in% c("REP", "DEM")) %>%
  group_by(cand_pty_affiliation) %>%
  summarize(size = n())

data
#> # A tibble: 2 × 2
#>   cand_pty_affiliation  size
#>   <chr>                <int>
#> 1 DEM                   1270
#> 2 REP                   1495

Data Visualization

We can visualize the above data:

library(ggplot2)

ggplot(data, aes(x = cand_pty_affiliation, y = size, fill = cand_pty_affiliation)) +
  geom_col() +
  labs(
    title = "Number of Candidates Affiliated with the Two Major Parties",
    x = "Party", y = "Count", fill = "Candidate Party Affiliation"
  )
