Summary

I worked on Micro task : https://github.com/bokeh/outreach-programs/issues/6 I was able to visualize the dataset using Bokeh. I converted the datetime column to Unix timestamps which made it possible for me to find the durations between pick up and drop off times. I also found the speed since we have the distance of the trip. I made visualizations using the distance, speed, durations, pick up and drop off times.

@whoisorioki Thank you for working on this microtask for your patience with our review. Your notebook looks great, and show how you've quickly familiarized yourself with Bokeh. :)

Some thoughts:

• I think you've created some unique and interesting visualizations here, this is the first time I'm seeing the taxi speed visualized. :)
• In your 2nd plot, titles "Histogram of pickup times" -- looks like we're plotting trip duration vs. frequency so I'd suggest updating the plot tile and x-axis label accordingly
• In the 3rd plot "Heatmap of pickup locations" -- I don't know if the plot is showing what you intended? Please correct me if I'm wrong, I'd suggest the following updates to start with:
  • Since you're mapping count to the colour, I don't think we need to use that for height as well. So you can fix both the height as well. Also, typically heatmaps are regular in shape, for example: https://docs.bokeh.org/en/latest/docs/user_guide/topics/categorical.html#heatmaps
  • I think the x-axis-label "Pickup location" will be more relevant, and you can consider removing the y-axis
• The last two plots seem like duplicates of previous ones, if that's the case I'd suggest removing them.

I liked the useful comments in your code, it made your work easy-to-follow. If you have the time, I'd encourage you to add some section headings for structure and notes about what you can infer from the plots for a story/flow in your notebook. :)

You've completed the microtask, please feel free to add this to your application after making any updates you see fit!
