What I Chose to Visualize
For this project, I decided to visualize the evolution of the most popular baby names in New Zealand from 2001 to 2010. The data I used was a ranking of the top baby names by year, which allows us to track trends over the course of a decade. I found it particularly interesting to see how popular names remained consistent but their rankings fluctuated.
Why a Bumpchart Was Appropriate
To convey this information, I used a Bumpchart, which I created using RAWGraphs 2.0. A Bumpchart is ideal for showing the ranking changes of items over time, as it allows easy comparison of categories (in this case, baby names) on a continuous timeline (the years 2001-2010). In this case, I was less interested in the absolute number of babies given each name but rather in the relative position of these names across the years. The bumping lines allow the viewer to quickly understand which names were stable over time and which ones experienced a rise or fall in popularity.
Changes to Improve Clarity
The initial presentation of the graph was difficult to interpret because all the streams (or lines representing different names) were in the same gray color, which made it hard to distinguish between them. To improve clarity, I applied the Spectral Discrete color scheme to the streams, which assigns distinct colors to each name. This allowed for better differentiation between the various names and helped draw attention to the trends without the viewer getting lost in the data. Additionally, I ensured that the axis labels and legends were clear and legible, adjusting font sizes and positioning for better accessibility. I also added a tooltip feature that provides more information about each name when hovered over, enhancing the interactivity of the visualization.
Reflection on Lin’s Lecture and DH Connections
In DH, visualizations often serve as a bridge between raw data and human understanding. Through this bumpchart, I was able to transform a collection of numerical rankings into something visually engaging and easy to interpret, which is one of the central aims of DH work. This visualization not only communicates a shift in name popularity but also provides insight into societal trends, such as cultural influences and generational shifts in naming practices. As DH increasingly incorporates data visualization, tools like bumpcharts provide a more intuitive way of exploring these trends, making the findings more accessible to a wider audience.

At first glance I thought the visualization would be hard to interpret with so much happening at once. But after looking at the graph and following some individual trend lines It was actually very easy to interpret the data. It was a good decision to color each name differently as this provides much clearer separation of the data. The relative thickness of the line is also a helpful differentiator. My only critique is the data which are interpreted as integers instead of years, though this does not effect analysis.
I think your visualization is eye-catching, but I personally don’t have the easiest time reading it. The addition of colors is an improvement from the grey it was originally, but there are instances where there are many similar yellow oranges close together. It also might be helpful to make the ‘M’ and ‘F’ labels more clear, or fully spell them out, or add a title to each image. On a first few glances, I did not see the labels.
