Inhalt: Power BI is rapidly becoming one of the most popular reporting and visualization tools and is a great way for non-technical users to build their own reports and data visualizations. However, Power BI comes with a rather limited set of standard visuals, and creating custom visuals can be a daunting process, one that requires JavaScript or TypeScript programmers. In this course, Emma Saunders shows programmers who are experienced at creating data visualizations on the web how to create custom visuals in Power BI. Emma starts with the basics of setting up your environment and installing the multitude of requisite files, then shows how to set up an account to access Power BI service. She explains the folder structure for the over 5,000 files you need for a single custom visual, before diving into the creation of custom visuals using single, categorical, and grouped data aggregation.

Inhalt: Need to slice and dice large and complex JavaScript data arrays with maximum speed and effectiveness? Enter Crossfilter.js. An alternative to expensive tools like Qlikview, Crossfilter manages the data that lie behind charts, allowing data scientists to group and filter data quickly and easily, right in the browser. Join Emma Saunders in this entry- through intermediate-level course, which explores data indexing and filtering with Crossfilter. Learn how to download and set up Crossfilter, create and use dimensions (which function similarly to properties) to filter data, group and reduce results, set up advanced filters to sort by range or function, and perform actions (like removals) on matching records.

Inhalt: Take your visualizations beyond boring charts. D3.js enables you to create spatial maps, tree diagrams, stack charts, and more, all with a web browser and a few lines of code. There's something for everyone in data science: statisticians, scientists, mathematicians, and analysts. D3.js Essential Training for Data Scientists unlocks the keys to this versatile approach. Follow along with data consultant Emma Saunders as she shows how to build beautiful and interactive data visualizations with D3. Start off with a review of HTML, CSS, and JavaScript-some basic coding skills you need to use the D3 library. Then learn how to make a simple bar chart and create basic shapes and text. Emma also introduces the path function and the power of generators for drawing more complex shapes. Then find out how to pull in JSON, XML, and CSV files to create more complex graphics such as tree and Voronoi diagrams, and manipulate your data for advanced graphics using map, stack, and nest functions. The course wraps up with tips for adding interactivity and picking the right graphic for your data. Umfang: 04:38:53.00
Inhalt: Dimensional charting (DC) allows data visualization to display in dashboard widgets as bar charts, scatterplots, heat maps, and more. DC.js is an open source JavaScript library based on Crossfilter and D3.js. In this course, learn how to build interactive, web-based dashboards. Instructor Emma Saunders covers all 20 built-in classes, the suite of included chart types, and the built-in formatting options available in DC.js. Learn how to use jQuery and bootstrap, apply filters, restyle existing dashboards, create custom charts, pair data using DC and D3, link charts, and more. Umfang: 05:03:23.00
Inhalt: Power BI is a software that lets users visualize and report data flexibly and share it in a number of ways. It is rapidly gaining market share, as it is affordable and well-integrated with other Microsoft tools. In this course, instructor Emma Saunders shows you how you can use Power BI to create reports and visualizations with flair and share them easily with colleagues. Emma explains the Power BI app (desktop) and service (web browser). She takes you through a sample report to show how it's built, then goes over how and why to design and structure a report, including how to structure tabs, how many visuals to put on a page, and how to draw attention to one visual over another. Emma covers more advanced visuals, as well, including statistical diagrams and maps for geographic data. She walks you through how to design reports like a pro in the Power BI service, from basic layouts to choosing specific themes and fonts. Umfang: 01:59:28
Inhalt: Do you rely on IT to get the data you need? Are you often stuck waiting in line for data, and wish you could just retrieve it yourself? In this course, learn how to get the data you want by writing a bit of SQL code. You won't just be able to pull data out of the database; you'll be able to manipulate it: merging it, grouping it, and relabeling it to get just the report you want. Join Emma Saunders as she shows how to write simple SQL queries for data reporting and analysis. Learn how to filter, group, and sort data, using built-in SQL functions to format or calculate results. Discover how to perform more complex queries, such as joining data together from different database tables. Last but not least, she introduces views, procedures, functions, and variables.
