This stacked bar chart displays two years of personal electricity consumption across three accounts in a three-family building, broken down by month. The visualization uses d3.stack to layer the account contributions, with d3.scaleBand for the x-axis, d3.scaleLinear for the y-axis, and d3.scaleOrdinal with d3.schemeCategory10 for color coding. The SVG is rendered as a group with margins, and interactive hover effects adjust bar opacity while title elements display individual usage amounts. The data is sourced from a personal electricity consumption dataset and processed with d3.group and d3.stack.

AI-generated description

A 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

  1. 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.
  2. 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.
  3. Changed the colors to green and blue. I thought they were less jarring.
  4. Cleaned up the code by grouping calculation of data with the code that added it to the visualization.
  5. Added a title to the accounts legend per feedback on slack.

Next steps

  1. Show a tooltip at the top of the bar amount when hovering over.
  2. 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.
