Proposition

Restricted abortion access between 2017 and 2020 experienced increases in abortion rates.

FOR the Proposition
Despite access restrictions, abortion demand is growing.
Abortion rates rose even in states that tightened access between 2017 and 2020.

Design Decisions and Rationale:

AGAINST the Proposition
Abortion rates remain stable throughout the country.
Nationally, abortion rates stayed largely stable from 2017 to 2020 despite policy shifts.

Final Reflection

When creating our visualizations, we decided that presenting our data through scatterplots was straightforward since it was already clean and easy to work with. The Plotly library made it simple to visualize a relationship between clinical access and abortion rate changes between different states. However, it was challenging to figure out how to present the data in a way that supported our specific propositions and made the trends appear more convincing. The scatterplots were our first attempt at visualizing the data, but we wanted to experiment with bar plots as well. However, it did not work out the way we wanted to. All the states were in the x-axis, and while it was easier to interpret the bars by comparing their lengths, having all states listed would only increase cognitive load, and we thought that the audience may spend more time and difficulty trying to understand our visualization, so we went back to using scatterplots. The biggest surprise was how much the title and a single fitted line shaped first impressions. Small choices such as scale, color, and whether to show a line changed what viewers believed before they inspected the points. We also made basic accessibility choices by using color-blind-safe defaults and points shaped as open-circles so that overlaps are visible without relying on color alone. Our audience is a general college classroom, so we favored simple encodings, neutral colors, and captions that reduce misreadings.

After creating our visualizations, we now define “ethical analysis and visualization” to be presenting data earnestly while also acknowledging context that was omitted. The design choices we made regarding titles, regression line, and axes ranges can guide audience interpretation, but maintaining ethics requires us to be transparent about our choices. We believe that transparency also draws the line between “acceptable” persuasive choices and “misleading” ones since highlighting a real trend is not only more acceptable, but also encourages the audience to explore the visualization compared to omitting data, which is more misleading because the audience may believe a proposed conclusion at face value.

However, there are limits to what these charts can claim. Clinic counts do not capture telehealth, travel across state lines, population change, or policy timing, so we cannot make causal claims from these plots. Framing matters because titles, fitted lines, and axis ranges can pull attention toward a story the data does not fully support. Persuasive choices are acceptable when they highlight real patterns in the data, but they become misleading when they imply causal conclusions the evidence cannot justify.If we were to improve our visualization, we would add a small multiples view by region or an interactive brush so readers can test subsets of the data for themselves rather than rely only on our framing.
