Projects

Datasets

Visualizations with D3.js

Draw Your data (spanish visualization): draw the visualization and download the dataset to generate that visualization.
MyAnimeList Visualization: explore animes releases from 1917 to 2021 with this visualization. Discover the most relevant words of the synopsis according to the anime’s genre. See how change the distribution of anime scores depending on the age-rating and its type. This visualization use the Anime Recommendation Database 2020 (kaggle).
SDGs Visualization (spanish visualization): explore the relationship between academic publications of the UC and the Sustainable Development Goals (SDGs).
DCC Requirements (spanish visualization): check the requirements of each course from DCC UC.
Banner UC vacancies (spanish visualization): Explore how to change UC course vacancies for each course enrollment starting in 2019.
Force Graph visualization (spanish visualization): check how to change the force graph when some parameters are edited.
Small Multiple with Idyll (spanish visualization): learn how use Idyll to create a scrollytelling visualization. (code).
Barchart with Piechart (spanish visualization): example of using the pie chart as a complement to a bar chart.
Bar Chart race compilation: visualize different datasets with an Bar chart race.
Language-Network: show language similarity based on the Levenshtein distance, a string metric for measuring the difference between two words. Work done by other people, but not currently working. I only edited the minimum necessary to make the visualization work again.
Museum MONA visualization (spanish visualization): artistic visualization to explore data about the Mona museum. Homework for the students of my course Visualization of information in 2022-2.
IMDB Movies visualization (spanish visualization): artistic visualization to explore data about IMDB movies. Homework for the students of my course Visualization of information in 2023-1.
Solar System visualization (spanish visualization): artistic visualization to explore data about Solar System. Homework for the students of my course Visualization of information in 2023-2.
Dragon Ball visualization (spanish visualization): artistic visualization to explore data about Dragon Ball in honor of Akira Toriyama. Homework for the students of my course Visualization of information in 2024-1.

Others

Monogatari (spanish project): create your own story with random cards.
Tic Tac Toe Version 2: play Tic Tac Toe where the tokens can eat the smallest tokens.
Anidle: guess the anime of the day.
