Showcase: Redesign

About VisiData

VisiData is a terminal spreadsheet multitool that can handle millions of rows faster than other spreadsheet tools with a GUI, such as Excel or LibreOffice Calc.

Uses for VisiData range from spreadsheet and data analysis to converting between formats, and even ASCII art.

In June 2021, I was contracted by Saul Pwanson, creator of VisiData, to redesign the open source project’s website.

Goals for the design


This website was originally built with a custom-made static site generator (SSG) and is a mix of regular Markdown files and reStructuredText parsed by pandoc.

I decided to use 11ty and TailwindCSS to build the site, as 11ty works well with Markdown files and the HTML-like Nunjucks templating language, combined with Tailwind, would be easy to update in the future.

Challenges overcome

reStructured Text

The docs were written in a mix of reStructuredText (RST) and Markdown, which proved a challenge as 11ty does not support RST. 11ty does support HTML files, so Saul wrote a script to run the docs through pandoc and output the resulting HTML files into a directory for 11ty.

VisiData documentation search

We needed a quick self-hosted solution to search the documentation, and rely on as few external dependencies as possible. This ruled out popular search engine Algolia, and led me to lunr.js, which can be fed a JSON file (generated by 11ty) of the index, and then run the search client-side in the browser. If JavaScript isn’t supported in the browser, the search results page falls back to a DuckDuckGo site search link.

DDG fallback

Updatable components

The site features 3 JSON files for easy updating of sections of the site that see frequent updates, including the sponsors in the footer area, the header navigation, and the testimonials.

Design highlights

Command demo

This demo existed prior to the redesign on the old site. I gave it a facelift and designed the terminal output area to use a monospaced font. If you select the text, the $ is left out, allowing for easy copy-and-paste of commands.

Features and Getting started

Using CSS Grid, I designed a highlighted features area with one block spanning two columns, making for a neat effect.

Releases and Blog lists on homepage

It’s important to quickly be able to catch up on what’s new with an open-source project. Adding the blog posts and releases list to the homepage was easily accomplished with 11ty’s post collections.
