A chart walks into a bar: Altair vs. leather
On the other hand, for the Y-axis, both charts present a scale with the same domain, ending in a nice round value (100). However, the number of ticks is different.

Building a Line Chart in React with VisX
Let's start small and build axes. To build axes, we need to define scales first. Under the hood VisX uses d3, so we it's really useful to review d3 scales documentation. D3 will use math to help translate our numbers to pixel locations inside the container.

Simple bar chart with React and D3 📊
Before we render our horizontal axis, we have to remember about scales. Scales are functions that are responsible for mapping data values to visual variables. I don't want to dive too deep into this topic, but if you're interested in further reading, you can check out scales documentation. We want our x-axis to display labels from data, so for this we will use scaleBand.

Build cool charts and visualize data with d3.js
We have used several utilities methods from d3 part of the scale module to correctly map our axis with the datas (scaleLinear, scaleBand). If you open your navigator you see now an svg element with two axis but no data yet.

How can better diversify the colors on my heat map?
Ah, sorry–misunderstood. Looking at your data it seems like you‘re mapping the raw values to color values, and you seem to have an extreme difference between values (high standard deviation). Try something like d3-scale to normalize the values and make them closer together (to be clear: you should still display the correct values to the user, but when visualizing them, you can use a more logarithmic scale to get a better color spread).

Open Source Adventures: Episode 59: What Opal Ruby is not
It's possible to build a framework on top of Opal Ruby, like notably Hypestack, which uses uses Opal and React. There are also some wrappers like opal-jquery, and I even created opal-d3 once upon a time, but I don't actively maintain it anymore.
