Visualizing Text Data Hierarchy with Word Trees

January 19th, 2023 by Julien Blanchard, Meta

Visualizing Text Data Hierarchy with Word TreesOver the past few weeks, I have been looking for a quick and effective way of representing the structural differences within a set of similar-looking short sentences.

To provide a bit of context, as we approached the end of 2022, my workmates and I got heavily involved in a planning phase for the new year to start. More specifically, we were asked to write a set of objectives and key results that would help drive a common strategy across our supported programs and pillars over the months to come.

And as expected, each and every one of us ended up leaving comments for every subtle change made to the couple of sentences that had initially been dropped into a shared document. As the comments started piling up, it quickly became quite tedious to follow and understand the slight modifications that were being made to our original set of objectives and key results.

As I started exploring what we could have done to better capture and visualise these changes, I recently found a way to display text data in a hierarchical way that I thought would be worth sharing.

How to Make Bubble Maps in JavaScript

November 16th, 2022 by Shachee Swadia

Bubble Maps in JavaScript HTML5Map charts are a great way to put data in a geographical context. And they are not difficult to create! I am eager to demonstrate that by walking you through the creation of a bubble map, one of the most popular types data maps, with the help of JavaScript.

A bubble map is a combination of a bubble chart and a geographical map. It uses circles of different sizes (and sometimes colors) to indicate numeric values relating to locations or territories.

In this tutorial, I will be visualizing the data on gasoline prices across the United States. They saw record highs this summer after a surge fueled by the outbreak of the Russia–Ukraine conflict. The first, basic bubble map will display the gas prices in July by state. The final one will add the magnitude of the change since February 23, one day before Russia launched an attack on Ukraine.

Follow along and you’ll learn to build beautiful interactive maps in JS with ease and no problem!
