Fork of Fork of Radial Stacked Bar Chart of Personal Electric Usage Data By Year for Account
This radial stacked bar chart visualizes two years of personal electricity consumption across three accounts, with monthly usage stacked by bill year. A menu lets viewers switch between accounts, triggering an update to the chart’s data via a reusable D3 component. The visualization uses d3.arc, d3.scaleRadial, and d3.scaleBand to render wedges, while d3.transition animates changes. Data comes from a CSV file of electric utility readings, and text measurement relies on the BrowserText helper using the Canvas API.
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
- Added the menu to choose accounts.
- Refactored the code into a reusable d3 component.
Next steps
- I still need to get the bar graphs to update. Made progress by getting console.log to work and I can see that update is getting called.
- Wrap the bar graph around a circle that is a 12 month period.
