In the grand theatre of data visualisation, dashboards act as the stage where insights perform and numbers tell their stories. But what happens when part of the audience can’t see the actors clearly, can’t follow the script, or can’t find the exit? Accessibility in dashboards is about ensuring that every viewer regardless of their abilities can understand, interact with, and act upon data with equal ease. The Hidden Walls of Data Visualisation Imagine walking into a room where the walls are painted in shades so similar they're indistinguishable, the lights are dim, and the signs are written in a tiny...

Introduction: When Uncertainty Becomes the Artist’s Brush Imagine standing before a vast canvas with no clear lines—just probabilities swirling like mist. Instead of a paintbrush, you hold randomness itself. Every stroke, every drop of chance, slowly reveals a pattern—a masterpiece shaped not by certainty, but by repetition and probability. That’s what Monte Carlo methods do. They transform randomness into precision, turning uncertainty into a reliable ally for solving the most complex problems in inference. From estimating the value of π to predicting financial risks and Bayesian posterior distributions, Monte Carlo simulations have become the invisible artisans behind modern computational science....
