Data Visualization with TREEMAPPER

Which keywords get more traffic and have good conversion rate compared to others? Which traffic sources get the maximum qualified visitors to your site? Which page is good at driving visitors or which engages a visitor well? You would often wish there was some visualization solution that could answer these question in one shot. My answer to this would be Treemapping! To begin with, lets understand what are Treemaps? Treemaps display hierarchical data as a set of nested rectangles. Now let’s go back to the questions we had at the beginning of the post. To exemplify, I’ve picked a site which has a lot of articles.

The Wikileaks war logs (The Guardian) What data visualization tools are out there on the web that are easy to use — and free? Here on the Datablog and Datastore we try to do as much as possible using the internet’s powerful free options. That may sound a little disingenuous, in that we obviously have access to the Guardian’s amazing graphics and interactive teams for those pieces where we have a little more time — such as this map of public spending(created using Adobe Illustrator) or this Twitter riots interactive. But for our day-to-day work, we often use tools that anyone can — and create graphics that anyone else can too. This online database and mapping tool has become our default for producing quick and detailed maps, especially those where you need to zoom in. Figure 103.

And these technologies are free, open and can be utilized in essentially every current web-browsing device. While it’s tempting to just jump in and add the latest cool feature to your site, you have to first make sure it’s a good fit for your users and your brand. In this 2-part series, I’m going to focus on the rapidly changing world of interactive tools for data visualization, or dataviz.

These tools are especially useful for nonprofits and financial organizations whose brands rely on sharing metrics to deliver impact and value. Data journalism. Retour sur la formation Datajournalism et Traitement des données. Les vendredi 26 et samedi 27 octobre 2012, l’association Libertic accueillait à la cantine numérique nantaise et avec le soutien de Nantes Métropole , Caroline Goulard de Dataveyes afin d’initier une vingtaine de participants aux principes de datajournalism et traitement de données.

In Part 1, we covered three cool tools for visualizing charts and graphs and many other data types on a webpage. In part two, we take a look at three more tools that are a bit more complex but have some incredible data visualization capabilities. 4. Simile Exhibit Exhibit is a very robust and customizable offering. Visualization Types Supported: Line Graphs, Maps, Scatter Plots, Multi-Filterable Lists, Timelines, Timeplots and more…with widgets! Flexible & Powerful Approach to Design I really like the approach of Exhibit, where data is presented through a “lens” – an HTML template shell that elements are placed into. Strong Filtering/Sorting/Search Letting users filter your data by any number of criteria is incredibly useful, and turns your information from static content into a real interactive feature.

Widgets! 5. 6. Wow, D3.js is cool! D3 isn’t really like the others. Junk Charts. This post is part 2 of an appreciation of the chart project by Google Newslab, advised by Alberto Cairo, on the gender and racial diversity of the newsroom.

Part 1 can be read here. In the previous discussion, I left out the following scatter bubble plot. This plot is available in two versions, one for gender and one for race. The key question being asked is whether the leadership in the newsroom is more or less diverse than the rest of the staff. The story appears to be a happy one: in many newsrooms, the leadership roughly reflects the staff in terms of gender distribution (even though both parts of the whole compare disfavorably to the gender ratio in the neighborhoods, as we saw in the previous post.)
