Fork of Electric Bar Chart Using d3.stack
A stacked bar chart displays two years of personal electricity consumption across multiple accounts within a three-family building. The SVG visualization uses d3.stack to aggregate data by account and date, with green and blue ordinal color encoding via d3.scaleOrdinal and d3.schemeCategory10. Axes are rendered using d3.axisLeft and d3.axisBottom, while hover interactions adjust rectangle opacity. A legend with account numbers appears in the upper-right corner, and the data comes from a CSV file loaded with d3.csv.
AI-generated descriptionA bar chart visualization of my personal electricity consumption dataset. I live in a three family structure and occupy two floors. There is also a common account that supplies the front and back hall lighting as well as the basement and exterrior outlets. It covers a period of two years.
I forked https://vizhub.com/RED98310/a3ea8fbec4b64423a7797a418de4af57?edit=files and stated with that code. I also looked at Most basic stacked barplot in d3.js for how to render the stacked barchart.
I made the following changes from the one last week
- Changed the code to use d3.stack. There was a bug in the previous week bar chart since it wasn't showing account number 2222222222.
- Changed the y axis label to be along the axis and vertical instead of horizontal and at the top to make room for the title.
- Changed the colors to green and blue. I thought they were less jarring.
- Cleaned up the code by grouping calculation of data with the code that added it to the visualization.
- Added a title to the accounts legend per feedback on slack.
Next steps
- Show a tooltip at the top of the bar amount when hovering over.
- Wrap the bar graph around a circle that is a 12 month period.
Unfortunately, I deleted the graph that I started with as part of cleaning up my profile then realized I should have kept it and forked from it per the instructions of the assignmnet. I believe I have captured all the changes.
