  • All the Ways to Make Bubble Tea, Taiwan's Pearl-fect Drink

    a sketchy illustrated vertical flow chart showing all the ingredients used to make pure teas, milk teas, milk based drinks, fruit juice teas, fresh juice, and priobiotics

    This piece took a simple question – how many unique bubble tea drinks are there in Taiwan? – and executed it delightfully. There’s so much information, but the illustrations and the personalized framing help you easily traverse it all. I am boba-obsessed, but I tend to stick with the same thing (jasmine milk tea, 50% sweet, light ice, boba), and this piece inspired me to try something new next time. —Michelle McGhee

  • Flags of Inequality

    a rainbow pride flag for each european country with each colored stripe's height calculated by the percentage of laws and protections for lqgbtq+ people in each category (red: equality and non discrimination; orange: family; yellow: hate crime and hate speech; green: legal recognition & intersex bodily integrity; blue: civil society space; purple: asylum). in 2022, malta ranked 1st, having the most laws and protections.

    The subject matter and the design collide with so much thoughtfulness and intention in this piece on LGBTQ+ rights in Europe. I keep looking at the rectangles and being amazed that those simple shapes hold so much meaning: the connection to the queer community, how each stripe is a building block for complete representation, and how the absence of color equals the absence of rights. The big idea behind this piece is so well done, but it’s also packed with so many small details — like how the flags reshuffle — that make the user experience more engaging. I like to consider myself a bit of a connoisseur of queer data projects, and this one is going to stay with me for a long time. —Jan Diehm

  • K-Means Clustering: An Explorable Explainer

    a square scatterplot with dots cluster in three areas. the areas are highlighted to show how k-means clustering works.

    I enjoyed everything about this explainer. I know a technical explainer is only meant for a specific audience, but it was done in a gentle and inviting way. It was clear that every piece of it was thoughtfully considered. The prose was both clear and approachable, the design was simple and clean, and the interactions were playful. There was also a nice balance of passive and active user experience. I appreciated the subtle additions, like toggling to the algorithm view, or dragging the edge handles for deeper control. All-in-all, it was a winner for me because it was able to teach me something in a pleasantly engaging way. — Russell Samora
