Think about this: These were drawn with ink and ruler in 1900. No computers. No design software. Every line, every color, every label — placed by hand. Du Bois and his Atlanta University students created 63 of these plates for the Paris World's Fair.
Du Bois and his Atlanta University students created these for a specific audience (the Paris Exposition) with a specific argument (counter the narrative of Black inferiority with DATA). Every design choice is rhetorical. The spiral is not just a chart — it's a visual argument about growth that is impossible to ignore. The color palette is not decorative — crimson, gold, and black carry cultural weight. The choice of what data to show is itself an argument about what matters.
Every visualization makes an argument. Can you find it?
Each hotspot reveals a different layer of meaning in Du Bois's visualization.
"Assessed Valuation of All Taxable Property Owned by Georgia Negroes." The title itself is an argument — it says: Black people own property, and we have the data to prove it.
Why a spiral instead of a bar chart? Because a spiral visually accelerates. As the value grows, the line sweeps wider and wider. The form makes growth feel dramatic and inevitable. This is a rhetorical choice, not a mathematical one.
1875 to 1899 — from just 10 years after the end of slavery to the turn of the century. The time range is chosen to show progress within living memory. Anyone at the exposition could see: this growth happened in less than a generation.
Bold colors against a light background. Du Bois used color not for decoration but for contrast and emphasis. The data line demands attention. Compare this to a modern "neutral" gray chart — which one makes you feel something?
Scholar note: What does the color choice communicate that the data alone doesn't? Why crimson and not blue? Why this aspect ratio? Compare to a modern chart of the same data — what's lost in translation?
Look at the plate above and answer: What is the title? What data is shown? What time range does it cover? What argument is it making? Write your answers before clicking the hotspots.
Pick a dataset about your community. Draw it like Du Bois would.
Choose a dataset below, then pick a visualization type. You'll draw it on paper first — ink and ruler, just like Du Bois.
Source your own data from the Census, your local government, or your school district. Choose the visualization type that makes the strongest argument — not just the one that displays data most clearly. Du Bois chose spirals when bar charts would have been simpler. Why?

Every color is an argument. Du Bois knew this 80 years before Tufte.
Du Bois didn't pick colors randomly. Crimson for the urgency of the data. Gold for the value of what Black Americans had built. Green for growth. Brown for roots. Every color choice tells the viewer how to feel about the data before they even read the numbers.
Du Bois's palette predates Edward Tufte's data visualization principles by 80 years. Compare his rhetorical color choices to the "neutral" palettes of modern tools like Tableau or D3's default colors. There is no neutral palette — every color is an argument. A gray bar chart says "this data is objective and unemotional." Du Bois's crimson says "this data is about people's lives." Which framing is more honest?
Pick 5 colors for your visualization. Think about what each color communicates about your data.
Now translate your hand-drawn visualization into code. Edit the template and watch it render.
Simple template: Edit the numbers and labels below. The chart renders in real time on the right. You don't need to know how to code — just change the values.
SVG tutorial: Code a Du Bois spiral from scratch using SVG path commands. The template below provides the math for the spiral, the color variables, and the data binding. Edit the code and watch it render in real time.
Du Bois's plates are in the Library of Congress. Yours could be too.

Data visualization is not decoration — it's argument.
Du Bois's plates are in the Library of Congress. They changed how people saw data and how they saw Black America. Your plate is part of that tradition. Every chart you draw is an act of seeing — and an act of showing the world what matters.
"Now art is not simply works of art; it is the spirit that knows Beauty, that has music in its soul and the color of sunsets in its handkerchiefs."— W.E.B. Du Bois, The Souls of Black Folk (1903)
