I wrote a script to scrape the technical specifications, ratings, and prices of all the Home Cinema AV Receiver reviews on What HiFi website because their search feature did not provide a means to filter reviews by anything useful, such as whether it is THX certified or not, or how many speakers outputs it supports.
In all, COUNT reviews have been scraped into my (MongoDB based) database.
The punchcard charts below provide at-a-glance view of the number of reviews which fall into each category. The area of each bubble represents the number of reviews. So bigger bubbles represent more data. Click on a bubble to filter data.
Use the controls at the top of the window to filter the data and enjoy the animations as you change values. (Press enter or move focus to trigger an update).
Click on headings to filter and sort by that column. Filtering removes 0 values (including 'false' for boolean columns).
