Today I put together my first dashboard! I used 3 different visuals: a map, a treemap, and a bar chart.
See this link:

The map allows the user to see where each sample site is located in the New Jersey/New York area. The relative sizes of each point (colored circle) signify the amount of total damage to businesses in the area. The sites are color-coded by region, but hovering over each also gives the region, sample site ID, and a breakdown of the total damage to different types of businesses.
Note: All three visuals are color-coded the same way, such that each region represented has the same color.
The treemap focuses on the total number of businesses damaged per site, with the sample sites labelled. They are also grouped and colored by their respective region. The relative sizes show the extent of damage to each site. Hovering over each rectangle displays the per site totals.
The bar chart focuses on the regions, with the length of the bar signifying the sum of all the businesses affected by flood waters of all the sites within each region.
The filter option (placed on the map) allows the user to choose to see all the regions or one specific region to view on the map and graphs.
I've now begun looking at my next set of data. So it continues...
Nice job in creating a nice gallery of visualizations you developed in just a week! You explained the graphs very well in your post. As you create more visualizations, I think you will start to see a more common thread of what story you can tell. I can also connect with the USGS team that created this data to help you think of what stories can be told with the visualizations you created.
ReplyDeleteSince you also took a field trip to ESRI, I think you would also enjoy exploring StoryMaps as another way to create spatial visualizations with a storyline. I hope you enjoyed the shorter journey to the ESRI R&D Center today in Arlington.
Same feedback as in the last post on the combined visualization. On the map, using color coding by location is redundant, since the map already shows location. Color coding by size (with big red circles showing lots of damage) would be a more effective use of color, since it would allow the view to scan the whole map and at a glance see where the most damage occurred. The size of the circles already does that, I realize, but in its current configuration the color tends to distract from that rather than reinforce it.
ReplyDeleteGreat work, btw!
