Concept
I used the same data from the last assignment which contained the number of checkout time for ten categories books in ten years.
The aim for the final project is to make visualization more clear that people can get information from the plot at first peek.
The basic shape was not changed but the arrangement became different.
Since there were exactly ten years and ten categories, I divided a circle into ten parts and made ten years data along the direction of split lines.
Compared to the last assignment, this project showed clearer comparison between each month in same year.
However, the trade-off was that user could not make comparison between different years.
As a result, I add a feature for user to check the data in specific month.
I designed two text field for month comparsion.
If user only enter one month, sectoral cylinders would show above the center circular plane.
If user types in another month in second textfield, the other sectoral cylinders would show in opposite direction.
*The height and size do not represent the true number of original data due to the high ratio between the maximum and the minimum.
Query
Inspiration
The original concept was from the travel website.
However, I did not find suitable data for this shape.
Moreover, the curve shape in 3D was hard to implement. Finally, it became more like a satellite.
Final result
