@ -26,7 +26,7 @@ At present several useful functions are implemented:
Return a list of maps, each representing one account from the `gaza.onl` database, with a key `:donations`, whose value is a float representing the total donations received by that account between the dates `start-date` (exclusive) and `end-date` (inclusive). Date arguments should be supplied as `java.time.LocalDate` objects, or as strings in the format `yyyy-mm-dd`.

### Saving charts as graphics files
Again, xchart provides facilities for saving charts as graphics files. To do this, in your REPL first invoke `(require '[com.hypirion.clj-xchart :refer [spit]])`. This will, obviously, over-ride `clojure,core/spit`. You can now save a chart as a graphic using, e.g.:
```clojure
(spit (chart-accounts-with-donations-by-months-in-range "2025-01-01" "2025-12-31") "donations-by-months-2025.svg")
```
The graphics format will be taken from the file extension, and at least all of `bmp`, `gif`, `jpg`, `png`, and, most importantly, `svg` are supported. The SVG is properly constructed as a drawing rather than as a raster, although there is no semantic labelling of the nodes or edges, which is disappointing.
## NOTE: Data
This code is designed to explore data in a [SQLite](https://www.sqlite.org/) database which it expects to be called `app.db` and find in its `resources` directory. This database is not included in this repository but may be downloaded from [here](https://gaza.onl/app.db).
