€1,600 per second. That’s how a lot curiosity Germany has to pay for its money owed. In whole, the German state has money owed ranging into the trillions — greater than a thousand billion Euros. And the federal government is planning to make much more, as much as one trillion further debt is rumored to observe over the following 10 years.
The numbers concerned in governmental funds are so big that one in all probability can not realistically assess simply how a lot even 1 billion Euro or Greenback are.
On this article, I reveal that standard lists and Charts fail to convey a way of simply how a lot cash is at stake relating to governmental spending. I then present how slightly little bit of programming can interactively visualize this cash and the way it pertains to different numbers. I’ll use Germany for example, because it at the moment receives a variety of media protection and its debt statistics are freely out there.
Plain enumeration
To start out, we’ll use plain enumeration of the important thing information as the primary methodology to (not) put info into relation. It excludes family money owed. As we’ll later see, this easy methodology totally fails in comparison with the visualization instruments supplied via easy scripts.
- €1,600: rate of interest per second
- €25,503: debt per German citizen if state debt is break up
And right here’s already a big soar for us. We’re immediately leaping into the billions:
- €49,5 billion: rate of interest per yr
- €100 billion: Sondervermögen (euphemism for debt) for German Military
- €500 billion: deliberate further debt for infrastructure
Now, we’re making one other soar:
- €2,11 trillion: whole German governmental debt (as of March 2025)
After studying these numbers, we’d know a bit extra about Germany’s debt. However we hardly have an understanding of how they relate to one another. Sure, we all know that €1 billion is a thousand occasions €1 million. However that’s simply frequent sense.
We might in all probability fare higher if we may see the numbers visualized aspect by aspect. That’s what we are going to do subsequent.
Linearly scaled charts
Utilizing python and the Matplotlib plotting library, it’s simple to create a easy chart. (Full code is linked on this article’s Useful resource part on the finish).
I picked 4 numbers to visualise collectively: €1,600 (as a result of most individuals know simply how a lot already that’s), €25,503 (as a result of it properly exhibits the hidden debt that any German has), €1 billion (as a result of that’s a really massive sum, one thing that enormous firms don’t even make per yr), and, lastly €49,5 billion (as a result of that’s how a lot Germany at the moment must spend simply in curiosity per yr which is greater than most international locations’ GDP).
import matplotlib.pyplot as plt
# Information
quantities = [1600, 25503, 1e9, 49.5e9, ]
labels = ['Per-sec. interest', 'Per-person debt','€1 billion', 'Yearly interest']
plt.determine(figsize=(10, 6))
plt.bar(labels, quantities, coloration=['orange', 'orange', '#03A9F4', '#ff0000'])
After working this code, we get the next plot:
What we see immediately: we don’t see the small cash. The large quantities utterly dwarf the €1,600. I’d wager to say that anyone studying this has extra connection to only €1,000 than to, say, €1 million. We all know what €1,000 may afford us. A few €1,000 is an effective month-to-month revenue for most individuals.
However the chart doesn’t even acknowledge it.
Is the error that I used linearly scaled axes? Let’s see subsequent.
Logarithmically scaled charts
In visualizing the information logarithmically, we’ll keep on with python and matplotlib. We merely want so as to add a single line of code and immediately get an up to date chart:

Is it higher? To some extent, sure! We are able to now start to see the distinction between on a regular basis quantities (just like the €1,600 curiosity per second) and the deliberate spending (i.e., debt).
Due to the logarithmic scaling, they seem on the identical chart. On this visualization, the chart doesn’t develop linearly, however logarithmically. Which means the spacing between two markers on the y-axis doesn’t signify a hard and fast, equal increment (like earlier than within the linearly scaled plot). As an alternative, every step represents a multiplication by a relentless issue. In our plot, the spacing is decided by multiplying with 100 (or, including two trailing zeros).
For our goal: is such logarithmic scaling higher than linear scaling? Sure, positively.
However, is it enough? Can we not do higher in attempting to convey what Germany’s as much as when it plans for €500 billion of further debt? And, how does this debt relate to different, already current money owed?
Sure, after all we are able to. Utilizing slightly little bit of HTML, JavaScript, and a few CSS styling, we are able to rapidly create a easy interactive webpage. For a newbie it’s simply doable over a weekend.
A static webpage is all it wants!
Information scientists and programmers wrangle with knowledge day-in, day-out. Instruments like Excel and python scripts assist them with remodeling the information to realize insights.
Generally, nonetheless, a easy webpage can convey the connection between numbers higher. Particularly once we are speaking concerning the big sums concerned in governmental money owed.
We begin our visualization in HTML, by stacking a couple of div-elements on prime of one another:
...
€25,503 (Debt per German citizen if whole governmental debt is break up )
...
For every part, we point out the quantity in € in an HTML attribute.
Subsequent, we are going to use JavaScript to rework the quantities into an easy-to-grasp-visualization.
For this, we outline that every pixel represents €1,000. By utilizing rectangular kinds, we are able to thus signify any amount of cash:
doc.addEventListener("DOMContentLoaded", operate() {
const wealthBars = doc.querySelectorAll(".debt");
wealthBars.forEach(bar => {
if (!bar.dataset.scaled) {
const quantity = parseInt(bar.dataset.top) / 1000;
const width = Math.min(Math.sqrt(quantity), 200); // Cap the width pixels
const top = quantity / width;
bar.fashion.width = width + "px";
bar.fashion.top = top + "px";
bar.dataset.scaled = "true";
Lastly, we add some CSS styling to make the rendered webpage look nicely:
.debt-wrapper {
show: flex;
flex-direction: column;
align-items: heart;
margin: 20px 0;
}
.debt-title {
font-size: 20px;
margin-bottom: 10px;
}
/* Debt Bars */
.debt {
place: relative;
transition: top 0.3s ease-out, width 0.3s ease-out;
background-color: #ffcc00;
max-width: 200px; /* Most width for bars */
}
Placing all of this collectively (discover the total supply code within the Assets part under), we get the next (I added additional key numbers that I thought of related in placing the German debt into proportion):

Now, that’s a straightforward to grasp visualization! You’ll be able to discover it your self right here: https://phrasenmaeher.github.io.
This straightforward webpage extra precisely represents the massive quantity of recent debt that Germany desires to make. Utilizing primary Programming expertise, we present how the debt pertains to on a regular basis sums (like €1,600) and current debt-related prices (just like the €49,5 billion curiosity per yr). Simply begin scrolling down, and also you get a way of how a lot cash it’s. Within the above GIF, we’ve not even scrolled 1% of your complete approach down (take a look at the scroll bar to the precise, it barely strikes).
Recall that 1 pixel equals €1,000. Even if you’re incomes €10,000 per thirty days, that’s merely 10 pixels, which is barely noticeable within the debt bars. In case you scroll simply 1 pixel down, you’ve gotten uncovered €200,000 of latest debt (with the default bar width of 200). Even when you make €1 million (per yr), that’s only a mere scrolling of 5 pixels. Nevertheless a lot cash you make, the visualization demonstrates: it’s actually a drop within the debt ocean.
If you’re German, I don’t really feel envy, particularly not for the upcoming generations: any person has to pay this again. Along with current money owed.
