Viewdata is very simple to use and navigate around and uses navigation similar to Google maps to move around the maps. Similar to Google Maps there will be difference based on the device you are using particularly if that device has a touch screen.
Zoom In and Out
To zoom the map in and out using a mouse use the mouse scroll wheel. To zoom using a touch screen use two fingers spreading them apart on the screen
Panning the Map
To move the map around using a mouse place the cursor on the map and while holding the left button down move the map to the desired location. To move the map using a touch screen use two fingers on the map and move the map to the desired location.
if you want to go to a particular location such as a suburb use the search function and the map will zoom to that location. See Search Function below for more details.
Splitting the Screen
Viewing my own data is great but to get the best out of this data you may want to view it alongside other data such as the demographic profiles that relate to your customers. This way you can see locations for particular sales and compare them to demographic or customer profiles.
The map can be viewed in either single or split view. You can toggle between each view by selecting the “Split Screen” or “Single Screen” button at the centre bottom of the map. When in split screen view you can slide the centre bar to the right or left to view more or less of each set of data. Census data is displayed on the left map view and User data on the right.
The legend gives an understanding of what is on the map, so the colours in each of the legend categories relate to a section of the map to show what each area represents. Use the legend with with map to identify areas with higher percentages of the category you are searching for. For example your ideal customers could have an income range that can be displayed.
Viewdata aautomatically displays a legend of the data that you have selected on the map. The legend is calculated and categorised into eight (8) segments. This is done using Quantiles. For an explanation of Quantiles click Here
Lets make it easy to see the area you are interested in. If your area of interest is a particular suburb then search for that suburb and go straight there raather than zooming and panning the map.
To Zoom the map to a particular area place the cursor in the search box and start typing your location you wish to go to. The suburb will appear in the list below the search box. Select your suburb and the map will zoom to that location.
Viewing Your Own Data
This is probably the first thing you are going to want to do. And is a simple as we can possibly make it. We have all heard the saying that a picture is worth a thousand words and it is so true. Visualising your data will reveal insights about where things have taken place such as sales or events of some kind and you will quickly be able to identify patterns just through viewing the data.
First select the “Your Data” button on the top right of the screen. There are two ways of bringing your own data into the application and viewing it. First is to click on the area just below Upload your Data and File Explorer will open. Simply select your CSV file and it will map it in the browser. The secon is to drag your file from the desktop and drop it into the browser. Both map the CSV file in exactly the same way.
When the map is produced the application also produces a set of graphs that are derived from the columns of data in your CSV file. Please see the section below on Filtering your data for an explanation of this function.
It is important that your CSV file is in a particular format so the applkcation knows how to map it and you get the most value from the information. To see some examples of this format and some sample data click Here
Selecting a Data Column to Count
To keep it simple Viewdata will always default to show Record Count and this just means that the aplication is processing data by the number of records in the spredsheet. So to keep it simple at first just leave this at the default. As you get more familiar you can venture further and follow the steps below.
When you map your own data the application does calculations to produce the graphs and maps based on the data in each of the columns. When Record Count is selected the application is doing calculation based on the number of records in the CSV file. This will most times be sufficient for your requiremnts. As you get more familiar with the power of Viewdata you can start to view the data by calculating using different columns such as a sales volume column for example or a sales margin column.
Selecting a Geography to Map
This bits easy. if you only have one geographical attribute such as postcode then thats all that is displayed. However sometimes you may have more than one in the data and this brings more opportunity. Viewing data at a higher level such as Local government area can be useful if wanting an overview but sometimes you want to view data at a suburb level if you are wanting to target a particular suburb with marketing.
Viewdata requires that there be at least one column in your CSV file with a geographical attribute to draw the map such as a Suburb or Postcode. You could have multiple columns of geographies in the CSV that are associated with each line of information. In this case you have the ability to choose which column you wish to produce a map with. Once you have chosen the geography the map will draw to that geography.
Filtering Your Own Data
Why filter you data? Its quite simple really, to uderstand it more. Lets look at an example. you have uploaded your sales data for the last year. In that data you have each of your sales along with what the sale price was and the profit made on each item, a common way of collecting data. You could look at all your sales or you could look at where you are making the most money, target that area and increase those sales to grow your profit.
Once your data is displayed, the application will create graphs from the columns of data in your CSV files. Each of these graphs can be selected to filter the data displayed on the map. For example if your CSv file contains sales by day of the week the graph will show each day of the week configured to show the number of sales on each day. If you select the graph for a single day the map will redraw to show the sales for that day only. You can reset the map to show all days of the week by selecting “reset” above each graph.
Opening the Data Menu
The Census data menu is on the left hand side of the map and can be opened by either selecting the arrows on the top left of the map or by selecting “Our Data” from the choices on the top right.
Selecting from the Data Menu
The data menus are built in a hierarchy to provide a gradually more detailed selection to map by. You can select from any of the data sets that hve an arrow beside them. Once you have chosen by selecting, that data set, it will be drawn on the map and a legend automatically generated.
Understanding the Graphs
Once you have selected some data to visualise on the map a set of graphs will also be displayed on the right hand side under Our Data. These graphs will initially show data for the whole country. Also the graphs will show information for data in the subset that you have selected. For example If you choose to display data on the map for Married people in the subset of Marital Status then all of the Marital status will be graphed. Hovering over the graph will show the percentages.
Selecting a Location on the Map
We are all interested in our own area to understand it better, and whn it comes to an area that we sell to its to gain an understandign of how to sell more or maximise the money we spend on marketing our products. So selecting a specific area wil give those insights.
Once you have selected some data to display you can also show more detailed information on the graphs by selecting a point on the map. Simply click on the map. An area will be highlighted on the map and data will display in the graphs just for that area.
Selecting a Comparison Area
Its all about context here. With any information how do you know if it is high or low unless you compare it to something else. So we offer the choice of selecting an area that you can compare your selection to. An example of this is how does that suburb income level compare to the rest of the state. It might appear high for example but when its compared it may be average.
Once you have chosen the Census data you want to display you have a choice of what geographical area you wish to compare it to. It is important to place the Census data into context by comparing it to another area such as the State or the whole country for example. This gives you an idea of how your selected area compares to state or country averages. To select a comparison area choose from the drop down menu and the graphs will redraw based on your selection.
Using the Buffer
So whats a buffer you ask. Quite simply it draws a circle from a point you select on the map. By doing this you can for example extract data from where something has happened such as a sale or a high level of sales.
You can show data in the graphs by selecting a point on the map or by selecting the buffer button. The buffer allows you to choose a radius from a point up to 1 Kilometre. Simply click on Buffer and select your desired buffer diameter from the drop down box. Then select a point on the map. A circle will draw at your desired diameter. Viewdata calculates the data by checking which SA2 geographies the circle intersects with. For an explanation of what SA2 Geographies are Click Here
