Funnel Charts are intended to show how the amount of something decreases through time, usually during some process. They consist of several blocks, where each block represents a part of a process, which has the exact number of something that we calculate. The lower the block is, the lower should be its value. If the value grows while the process is going on, this funnel chart becomes a pyramid.
This Chart shows how people describe their connection with a brand in a Nation Wide survey. The first block shows all people who were surveyed. The next block shows how many recognized a brand. The third block represents those who follow brand news in Social Media. Then we see the people who are considering buying products of a given brand, and then those who at least once purchased. Next the bottom of the funnel we see loyal customers (sometimes referred to as loyalists) and Brand Evangelists (Advocates) at the very bottom.
Each block is colored differently, and each block can be selected separately by click. If you need to select several blocks of a funnel, hold the Shift or Ctrl key while selecting the blocks. Funnel legend is disable here, parts are identified by labels connected with them by connector lines.
