 Sqliteviz is a single-page offline-first PWA for fully client-side visualisation of SQLite databases or CSV files.
 
 With sqliteviz you can:
-- run SQL queries against a SQLite database and create [Plotly][11] charts based on the result sets
+- 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
-- manage queries and chart settings and run them against different databases
-- import/export queries and chart settings to/from a JSON file
+- export result set to CSV file
+- manage inquiries and run them against different databases
+- 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

+# SQLite WebAssembly build micro-benchmark
+
+This directory contains a micro-benchmark for evaluating SQLite
+WebAssembly builds performance on typical SQL queries, run from
+`make.sh` script. It can also serve as a smoke test.
+
+The benchmark operates on a set of SQLite WebAssembly builds expected
+in `lib/build-$NAME` directories each containing `sql-wasm.js` and
+`sql-wasm.wasm`. Then it creates a Docker image for each, and runs
+the benchmark in Firefox and Chromium using Karma in the container.
+
+After successful run, the benchmark result of each build is contained
+in `build-$NAME-result.json`. The JSON result files can be analysed
+using `result-analysis.ipynb` Jupyter notebook.
