Fork of Fork of Electric Bar Chart Using d3.stack
This visualization displays two years of personal electricity consumption across multiple household accounts, shown as stacked bar charts organized by month. Each month’s bar is segmented by account number, with green and blue colors distinguishing the accounts, and hovering reveals exact kilowatt-hour values via tooltips. The code uses d3.stack to transform the dataset, d3.scaleBand and d3.scaleLinear for axes, and d3.scaleOrdinal with d3.schemeCategory10 for colors. It renders with SVG, includes a legend, and is built from a CSV data file.
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.
