 # sqliteviz
 
-Sqliteviz is a single-page offline-first PWA for fully client-side visualisation of SQLite databases or CSV files.
+Sqliteviz is a single-page offline-first PWA for fully client-side visualisation
+ of SQLite databases, CSV, JSON or NDJSON files.
 
 With sqliteviz you can:
 - run SQL queries against a SQLite database and create [Plotly][11] charts and pivot tables based on the result sets
-- import a CSV file into a SQLite database and visualize imported data
+- import a CSV/JSON/NDJSON file into a SQLite database and visualize imported data
+- export result set to CSV file
 - manage inquiries and run them against different databases
-- import/export inquiries to/from a JSON file
+- import/export inquiries from/to a JSON file
 - export a modified SQLite database
 - use it offline from your OS application menu like any other desktop app

+This directory contains a micro-benchmark for evaluating SQLite WebAssembly

+the script has permission to `nice` processes and [Procpath][1] is installed,
+e.g. it is run with `sudo -E env PATH=$PATH ./make.sh`, it'll `renice` all
+processes running inside the benchmark containers. It can also serve as a smoke
+test (e.g. for memory leaks).
 
-The benchmark operates on a set of SQLite WebAssembly builds expected
-in `lib/build-$NAME` directories each containing `sql-wasm.js` and
-`sql-wasm.wasm`. Then it creates a Docker image for each, and runs

+These files can be analysed using `result-analysis.ipynb` Jupyter notebook.
+The SVG is a chart with CPU and RSS usage of each test container (i.e. Chromium
+run, then Firefox run per container).
