  • Example:

      ## Fetch data
  library(DBI) # Sqlite
  con <- dbConnect(RSQLite::SQLite(), "org-roam.db")
  dbListTables(con)
  links <- dbSendQuery(con, "SELECT [from], [to] FROM links")
  links <- dbFetch(links)
  titles <- dbSendQuery(con, "SELECT * FROM titles")
  titles <- dbFetch(titles)
  dbDisconnect(con)

  ## Create edge list [from - to] with clean labels
  library(dplyr) # Transformation
  library(stringr) # String manipulation
  edges <- inner_join(links, titles, by = c("from" = "file")) %>%
    inner_join(titles, by = c("to" = "file")) %>%
    select(From = titles.x, To = titles.y) %>%
    mutate(From = str_sub(From, 3, -3), # Clean titles
           From = str_replace(From, '" "' ,"/"),
           To = str_sub(To, 3, -3),
           To = str_replace(To, '" "' ,"/"),
           )

  ## Visualise and save as png

  par(mar = rep(0,4))
